title: Fetch Google Default account in case of multiaccount session
body: <p>Is it possible to fetch default Google account? </p>
  
  <p>I checked the documentation around <a href="https://developers.google.com/docs/api/quickstart/php" rel="nofollow noreferrer">PHP Quickstart</a> and <a href="https://developers.google.com/identity/sign-in/web/sign-in" rel="nofollow noreferrer">JS client-side auth</a>. As result I didn't find any functional like fetch default account in case of multi account Google account session.</p>
