Based on issues that Coleton surfaced with the current guide.

@ColetonS are there any further updates you want to make to this guide, or should I close this issue?

Hi @ashryanbeats. I just had the issue with the scopes: https://adobeio.slack.com/archives/G019MTCFPKR/p1607013378001200. But maybe this has already been addressed.

@ryanstewart can you verify which scopes should be used for Events? There is a list of scopes here:

But it doesn't seem people are having success with these scopes.
