Our playlists always included the possibility to define shared users, up until now if a user created a playlist his username was added to that list and that was it.

Since jellyfin/jellyfin#9466 the creator gets set as OwnerUserId which always has full access and any other user can be added to Shares with readonly or write permissions.
Additionally the playlist can be marked as OpenAccess which gives all users read permissions.

The items within a playlist are filtered for each user, so even if the playlist includes restricted items, they are hidden for users without access to those items.

Expected Behavior

• Interface should provide means to add and remove users to Shares with the ability to give and revoke edit permissions
• Interface should provide means to set a playlist as OpenAccess
