title: Understanding Sign-in process in actions-on-google
body: <p>I have a Google Assistant (Actions on Google) app where I want the user to log in. I use actions-on-google with DialogFlow which in turn has a webhook.</p>
  
  <p>For a specific action where signin in required, in the webhook, I launch app.askForSignIn();</p>
  
  <p>I have an intent called actions.intent.SIGN_IN which has an event called actions_intent_SIGN_IN. On this action, I check app.getSignInStatus() and I get null for this.</p>
  
  <p>Am I missing something? Will Google Assistant / Actions on Google do something to extract link the token and scopes from oauth and associate it with the user?</p>
