I literally pasted these two lines into ChatGPT that were sent to me by one of sysadmin and it told me exactly what I needed to know:

    App1: requestedAccessTokenVersion": null
    App2: requestedAccessTokenVersion": 2

I use it like that all time. In fact, I'm starting to give it less and less context and just toss stuff at it. It's more efficient use of my time.
