How to make telegram login widget work in android webview?

Question

Android

There is a webview project in android studio. The site has an authorization plugin through widget telegram.
https://core.telegram.org/widgets/login
Authorization works through the browser, if you use webview it gives

bot domain invalid

All basic "settings" are included:

mWebView.getSettings().setDomStorageEnabled(true);
                        mWebView.getSettings().setJavaScriptEnabled(true);
                        mWebView.getSettings().setLoadsImagesAutomatically(true);
                        CookieManager.getInstance().setAcceptCookie(true);
                        mWebView.getSettings().setAppCacheEnabled(true);
                        mWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);

If you write the following, the widget is not called (I myself have not used such settings in webview projects for the last 3 years):

mWebView.getSettings().setSupportMultipleWindows(true); mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

Usually, a bot domain invalid error is issued if the domain is not linked to the bot in the botfaser. But here the problem is with webview. Who will prompt where to dig?
Thank you.
