Ok, you see here we are taking the user idToken as Observable. I am not sure is it a stream or signal but for reactive programming it's very critical

Stream — A stream of discrete events. Also known in other FRP systems as an event, like keyboard input events, WebSocket events, login/logout events etc. (in rxjs — Subject, Observable)

Signal — A container/store for a value that changes over time. Some FRP systems call it a behavior, property, cell or signal, like isLogin state, key press state, current user state etc. (in rxjs — BehaviorSubject, ReplaySubject(1), shareReplay(1)).

For example in Angular components @Output is a stream, and @Input is a signal

	export function isWebview() {
	const navigator = window.navigator;
	const userAgent = navigator.userAgent;
	const normalizedUserAgent = userAgent.toLowerCase();
	const standalone = (navigator as any).standalone;

	const isIos =
	/ip(ad\|hone\|od)/.test(normalizedUserAgent) \|\|
	(navigator.platform === 'MacIntel' && navigator.maxTouchPoints > 1);
	const isAndroid = /android/.test(normalizedUserAgent);

	import { BreakpointObserver } from '@angular/cdk/layout';
	import {
	Directive,
	EmbeddedViewRef,
	Inject,
	inject,
	InjectionToken,
	Input,
	OnDestroy,
	TemplateRef,
