Google Login in Webview

Is there any way by which if we are using a webview , we can enable Google login for the user .
There was a youtube video posted in community about google login but it only talks about if we add our button then only it can be used.
Getting error when trying to login. Any blocks or doc will be helpful.

You can try using Custom Chrome Tab

Do you have any blocks or anything to facilitate this. If you can share that it will be really helpful.
