After installing StartUML successfully, modify LicenseManagerDomain.js as follow:

/**
 * File name: LicenseManagerDomain.js
 * Mac OS: /Applications/StarUML.app/Contents/www/license/node/
 * Linux: /opt/staruml/www/license/node/
 */

(function () {
    "use strict";
 
    var NodeRSA = require('node-rsa');
 
    function validate(PK, name, product, licenseKey) {
        return{
           name: "sontd",
           product: "StarUML",
           licenseType: "vip",
           quantity: "unlimited",
           licenseKey: "no, thanks!"
        };
    }
 
    function init(domainManager) {
        if (!domainManager.hasDomain("LicenseManager")) {
            domainManager.registerDomain("LicenseManager", {major: 0, minor: 1});
        }
        domainManager.registerCommand(
            "LicenseManager", // domain name
            "validate",       // command name
            validate,         // command handler function
            false,            // this command is synchronous in Node ("false" means synchronous")
            "Validate License",
            [
                {
                    name: "PK",
                    type: "string",
                    description: "PK"
                },
                {
                    name: "name",
                    type: "string",
                    description: "name of license owner"
                },
                {
                    name: "product",
                    type: "string",
                    description: "product name"
                },
                {
                    name: "licenseKey",
                    type: "string",
                    description: "license key"
                }
            ],
            [
                {
                    name: "result", // return values
                    type: "object",
                    description: "result"
                }
            ]
        );
    }
 
    exports.init = init;
 
}());

Now, open it and go to Help > Enter License and you have to write the name and the licence key which you have written on LicenseManagerDomain.js. In this example would be the next:

name: "sontd"
License Key: "no, thanks!"

Enjoy it!

Hello, my language is not English, so I will use a translator.
I did the following and it worked for me on Linux (StarUML v6.2.2).
Modify the entire contents of src/engine/license-manager.js
(to find the file I followed the instructions in one of the previous comments)

const { EventEmitter } = require("events");
const fs = require("fs");
const path = require("path");
const UnregisteredDialog = require("../dialogs/unregistered-dialog");
const packageJSON = require("../../package.json");

const PRO_DIAGRAM_TYPES = [
  "SysMLRequirementDiagram",
  "SysMLBlockDefinitionDiagram",
  "SysMLInternalBlockDiagram",
  "SysMLParametricDiagram",
  "BPMNDiagram",
  "WFWireframeDiagram",
  "AWSDiagram",
  "GCPDiagram",
];

var status = true;
var licenseInfo = {
  product: packageJSON.config.product_id,
  licenseType: "free", 
  quantity: 1,
};

/**
 * @private
 */
class LicenseManager extends EventEmitter {
  constructor() {
    super();
    this.projectManager = null;
  }

  isProDiagram(diagramType) {
    return PRO_DIAGRAM_TYPES.includes(diagramType);
  }

  /**
   * Get Registration Status
   * @return {string}
   */
  getStatus() {
    return status;
  }

  /**
   * Get License Information
   * @return {Object}
   */
  getLicenseInfo() {
    return licenseInfo;
  }

  /**
   */
  validate() {
    return Promise.resolve(licenseInfo);
  }

  /**
   */
  async checkLicenseValidity() {
    setStatus(this, true); 
  }

  /**
   *
   * @param {string} licenseKey
   */
  register(licenseKey) {
    return Promise.resolve(licenseInfo);
  }

  htmlReady() {}

  appReady() {
    this.checkLicenseValidity();
  }
}

module.exports = LicenseManager;

It worked for me so far, I hope it works for someone else too.

For ease of use, I took the license and watermark management logic and put it into a bash script, if that helps people code

There is a problem when exporting the file to image (PNG, JPG), the App will ask for licenseType and this code is null, so it unable to export the Image

update function below to fix it, i didn't test on PRO Diagram yet, but it's working for export image

var licenseInfo = {
  licenseType: "PRO",
};

register(licenseKey) {
    return new Promise((resolve, reject) => {
      var data = {
        product: packageJSON.config.product_id,
        licenseKey: licenseKey,
        licenseType: "PRO",
      };
      var file = path.join(app.getUserPath(), "/license.key");
      fs.writeFileSync(file, JSON.stringify(data, null, 2));
      licenseInfo = data;
      setStatus(this, true);
      resolve(data);
    });
  }

Hello, my language is not English, so I will use a translator. I did the following and it worked for me on Linux (StarUML v6.2.2). Modify the entire contents of src/engine/license-manager.js (to find the file I followed the instructions in one of the previous comments)

i changed the file. It still kept showing that my license has expired.
