I am trying to implement an app that will load the same data across devices in the same family sharing purchase. I can see how you can set a custom user id, but can you get it back when checking for permissions on another device?
example:

1. phone 1 purchases subscription and sets some custom property (UUID).
2. phone 1 adds data firebase with that UUID as a key
3. phone 2 checks for permissions and (I'm assuming) gets confirmed it has permissions.
4. is that UUID able to be returned to phone 2 so it can then look up the data in firebase?
   If not, how is it suggested to be done?
