Creator.Ionic AngularFire login with Google

Hello,
I am trying to use AngularFire (x1.6) for google login, and, there are no useful documentation on how to access cordoba’s config.xml

I am following this tutorial: https://firebase.google.com/docs/auth/web/cordova
and this: https://docs.usecreator.com/docs/how-to-use-cordova-plugins-with-your-creator-app

However, I guess I cannot test it without exporting it to CLI?
