I can't see why it wouldn't work. The specs for the display say it's an ordinary Thunderbolt over USB-C. Have you tried just plugging it in? Should work just fine with a MacBook too even though the laptop probably can't act a as a monitor, of course.
The nice thing about syncing services like Vaultwarden is that all your synced devices kind of act like backups. You should still keep proper backups too, of course, but this makes me sleep a bit better at night at least.
