More information I can get from OAuth?

I used Google OAuth in my code

      requestPermissions: ['email']
    }, function(error) {
      if (error) {
        console.log(error); //If there is any error, will get error here
      } else {
        const user = Meteor.user();

I can only get name from user, and when I used a third-party google account, the username is empty. I was wondering wether there is any other way that I can get user information from Google OAuth.

I suppose you have to go ask for it. Search for google api, you’d pass in access token into api call.
