Load the Google 3P Authorization JavaScript Library

Be sure to load the Google 3P Authorization JavaScript library on any page a user might load OAuth 2.0 codes or tokens. Use the following code snippet:

<script src="https://accounts.google.com/gsi/client" onload="console.log('TODO: add onload function')">
</script>

You can optimize your page's loading speed if you load the script with the async and defer boolean attributes.
