OAuth scopes

[laurentpayot]

Hi, I’m evaluating Instant to rewrite a Firebase app.

I just added Google OAuth (redirect flow) to my POC Instant app and I was surprised to see that I can only get the email of the user. How can I add all the other scopes (full name, picture url etc...) as defined in Google OAuth docs?
In Firebase, it is as simple as provider.addScope("profile").

Thanks for your nice product!
