firebase auth addScope question

[qiquanlu]

Hi firebase team,

I followed your doc here

• 2, Specify additional OAuth 2.0 scopes.

I added following code try to get user's firstName & lastName value

provider.addScope('https://www.googleapis.com/auth/userinfo.profile') 

I can see the values are being returned for the post request https://identitytoolkit.googleapis.com/v1/accounts:signInWithIdp?key=xxxxxxxxxxxxxx when inspecting browser network section,

but not be able to get it from the firebase response.

Is this an expected behavior or there is something I missed?

Thanks

I figured it out, need to call getAdditionalUserInfo(resp) to get additional user information.

It would be helpful to include a link of https://firebase.google.com/docs/reference/js/auth#getadditionaluserinfo within the Specify additional OAuth 2.0 scopes doc
