If the idea https://github.com/immich-app/immich/issues/265 is developed:

• As connected user in mobile app, I receive a friend url for his immich album. When I open the lick, the Immich app open and a "Shared album" section show this new public album in my app.

• As unconnected user, if I receive a friend url to access a public album -> I can view the album in the app, or I need to type a nickname to visualize/edit the album.
