  <p>I am following Rajat's answer and have done till the 2nd step. </p>
  
  <p>But I am not getting the accessToken in the user's object. I neeed this token to get the user details from this api endpoint: "<a href="https://www.googleapis.com/oauth2/v1/userinfo?access_token=" rel="nofollow noreferrer">https://www.googleapis.com/oauth2/v1/userinfo?access_token=</a>" </p>
  
  <p>Instead I am getting this user object from the fulfillment JSON: <code>{ locale: 'en-GB', userId: '15391770952311649498774' }</code>.</p>
  
  <p>How can I get the access token?</p>
