Enable Firebase Authentication with Google account

Hello! How I can enable the authentication using Firebase Authentication with a Google account?

I need to my application, but I don’t find the tutorial or something like this in some place, so someone can help me? Basically, what I want is: click on a button and open the popup to user make the login. The account need be save in Firebase too.

I should use HTTP request, custom JavaScript, the component WebView or the component HTML renderer? I’m very lost, even reading the most of documentation. I aprecciate the help!

Sorry for bad English, by the way.
