Document X-Goog-PageId
Context: I am setting up mopidy-ytmusic on NixOS. There isn't access to mopidyctl for some reason, so I've had to manually fill out the auth.json
I was having a strange issue where authentication was succeeding, but I wasn't getting back the correct data for my account. I think the problem is that I've accidentally been using a brand account for my music. I attempted to follow the ytmusicapi FAQ to resolve this, but changing the AuthUser just made authentication fail. However, I noticed the X-Goog-PageId had the same value as my brand id, so I went back to my previous auth.json and added the X-Goog-PageId field. Everything seems to work now!
I haven't seen any info on this particular scenario, so I'm creating this issue to have the X-Goog-PageId field documented.
I don't think the X-Goog-PageId field is even required, for my requests from brand accounts it works just fine without.
Do you think it is needed?
