@bertusjwz @manovee @Benso254 It still works, don't know if you still need it, but someone might.

Here is the whole code:

function hideTdo() {
  var timer = null;
  var target = document.querySelectorAll('#tidio-chat iframe')[0];
  if(!target || typeof target === 'undefined') {
    if(timer !== null) {
      clearTimeout(timer);
    }
    timer = setTimeout(hideTdo, 500);
    return;
  } else {
    var timer2 = null;
    var tdo = document.querySelectorAll('#tidio-chat iframe')[0].contentWindow.document.querySelectorAll('div.input-group a.powered')[0];
    if(!tdo || typeof tdo === 'undefined') {
      if(timer2 !== null) {
        clearTimeout(timer2);
      }
      timer2 = setTimeout(hideTdo, 1);
      return;
    }
   document.querySelectorAll('#tidio-chat iframe')[0].contentWindow.document.querySelectorAll('div.input-group a.powered')[0].style.display = 'none';
	 setInterval(function(){ hideTdo(); }, 1);
    return true;
  }
}
hideTdo();

Hello..

After adding the function to hide tidio logo in bot im unable to see URL links in conversations, Its hiding URL links after adding this code along with logo.....What i have to do plz help..

below one is far better
(function() {
function onTidioChatApiReady() {
document.querySelector('#tidio-chat iframe').contentDocument.querySelector('a[target=_blank]').remove();
}
if (window.tidioChatApi) {
window.tidioChatApi.on("open", onTidioChatApiReady);

} else {
document.addEventListener("tidioChat-open", onTidioChatApiReady);
//console.log("listener");
}
})();

use below:
document.querySelector('#tidio-chat iframe').contentDocument.querySelector('form').nextSibling.remove();

instead of below:
document.querySelector('#tidio-chat iframe').contentDocument.querySelector('a[target=_blank]').remove();
