change plublic/private for existing playlist

[deafhobbit]

recently, i lost all the music playlists i had previously build on my truenas scale jellyfin server. the playlists all still existed, but they had all been set to include zero songs. i don't know why this happened, and will look into it eventually, but that's not today's problem. 

thankfully, i was able to recover my old playlists by cloning an old zfs snapshot, copying out everything from /config/data/playlists/, and pasting that back into the the same directory in the current version. issue is - all of these playlists appear to have been set to private when i did this. previously all users were able to see all of them, but now users can only see the ones they created.

i can create new public playlists all users can see, so i'm sure i could fix this by re-creating them, but that would be very time consuming. is there any way to change an existing playlist from private to public? i can't find an option for this in the gui, and i don't see a private/public flag anywhere in the playlist.xml files.

thanks!
