title: GoogleSignIn - How to refresh the access token? Can't find anything on it in the docs
body: <p>I've successfully integrated <code>GoogleSignIn</code> into my Android app, but after 1 hour, the access token expires. How do I refresh the token?</p>
  <p>I've checked out the entire docs for <code>GoogleSignIn</code> but there's nothing on refreshing the <code>accessToken</code></p>

  <p>I've also tried searching for a method that has something like &quot;.refreshAccessToken()&quot;</p>

  <p>How do I refresh the token? Why is there nothing about it in the docs?</p>
