NSB AppStudio Google Account Sign In Integration

Hello! I am currently working on developing a JavaScript application for one of my BIA classes, and I’ve been trying to integrate a Google account sign in page with little success. I’ve been following the instructions found on this discussion board ( Integrating Google Sign-In into Nsb App ), although I’ve been having issues understanding how to utilize oauth, and how it works in to developing my application. I’ve created a google services account and have the API key set up, however I’ve been getting lost beyond that point. Any advice you can offer would be greatly appreciated!

Wasn’t Google+ shut down by Google on April 2, 2019?

Ah, my apologies–I was mixing up Google+ and Google Account Sign in. I would like to use google account sign in for the application.
