Taking ownership of an album as an admin / sharing non-owned album

I was on a trip with several people, one of which have already been onboarded to immich beforehand. He created an album where two of us uploaded our photos.

Now I wanna share the album trough link to people without account, but since I am not an owner of the album, I cant do it.
How do I "take ownership", or allow myself to do it?
I have admin account, and immich instance is running on my server.
