Hi, 

As part of a project, I need to integrate with Google Slides. There is a Forge component but the Authentication uses deprecated Sign in methods.

I've created a Client_ID and registered the app in the developer console of google, however when I try to log in I get:

'You have created a new client application that uses libraries for user authentication or authorization that are deprecated. New clients must use the new libraries instead. See the [Migration Guide](https://developers.google.com/identity/gsi/web/guides/gis-migration) for more information.'

I've been looking at the Migration Guide, but it hasn't really been much help. There's almost too much information.

Does anyone know a Forge Component that has updated Libraries that allow you to Sign in/Authenticate in order to use Google Slides? Or any OS guides there that would show how to do this?

Thanks in advance for any responses!
