What part(s) of the page would you like to see updated?

Hey team, wanted to reality check the GBQ OAuth configuration step "Set up an OAuth consent screen if you haven't already" as quoted from here. Part of setting up OAuth consent is the opportunity to specify scopes, as shown in the screenshot. I've tested it both ways, and it appears that it is not necessary to specify scopes. However, this may be confusing to the user. I would strongly recommend that we spell out in our docs what is needed and what is not needed in the OAuth consent screen.
