title: google oauth prefill account email
body: <p>How can I prefill the account when using the oauth service of the google api. It asks me to enter the email address. I have other extensions installed that already have the gmail account selected for me. This is what it looks like when I initiate it:</p>
  
  <pre><code>        var opts = {
              interactive: true,
              url: `https://accounts.google.com/o/oauth2/v2/auth?client_id=${clientId}&amp;scope=${scopeParam}&amp;redirect_uri=${redirectUrl}&amp;response_type=token`
          };
  
  chrome.identity.launchWebAuthFlow(opts, authUrl =&gt; {...});
  </code></pre>
