Google Login not visible in WebView

Hello All
Recently I Try to convert my Website into App using WebView. I Use Custom Webview Extension. Everything works fine except Google Login
It Works fine in Website but Google Login Button not visible in Webview.

I Searched over Community but not get any effective way.
I request you all to help me to solve this issue.

Best Regard

Can you share the screen shots or video recording?

This is from webview
