Firebase 3 - Additional Auth Scope Data
<p>In the Firebase 3 documentation, they say you can grab additional scope data such as this one:</p>

<blockquote>
  <p>Optional: Specify additional OAuth 2.0 scopes that you want to request from the authentication provider. To add a scope, call addScope. For example:
  <code>provider.addScope('https://www.googleapis.com/auth/plus.login');</code></p>
</blockquote>

<p>Once authenicated, I can't find the data as part of the "user" object. Any idea how to pick that extra data ? </p>

<p>Thank you,</p>
