title: Google Smarthome Action account linking missing user information
body: <p>my code is based on this example<br>

  <p>The OAuth process is working. But now I want to know who is the user.</p>
  
  <p>Here<br>
  <a href="https://developers.google.com/assistant/identity/google-sign-in-oauth?oauth=code" rel="nofollow noreferrer">https://developers.google.com/assistant/identity/google-sign-in-oauth?oauth=code</a><br>
  is described that:<br>
  <em>After the user gives your Action consent to access their Google profile, Google sends a request that contains a signed assertion of the Google user's identity.</em></p>
  
  <p>But if I test the authentication I never will be ask to give access to my Google profile.</p>
  
  <p>I think that I have to configure which information my app wants to have from the user. But I didn't know where to do that.</p>
  
  <p>I searched a lot but I couldn't find an example which really explains how to get the user information.</p>
  
  <p>Thank you for your help.<br>
  Regards Simon</p>
