Question regarding Kopia UI vs restic, etc.

I have a small client on the side that I am looking to get more durable off-site backups done. I personally use restic and resticprofile in my homelab without issue. The issue is that I would like to give them some kind of GUI and from what I see, none of the restic ones will do it.

Kopia appears to be roughly the same kind of design so I'm wondering about the KopiaUI. I would be running the backups themselves off the file server itself but would like a GUI to be available via either a desktop OR at least exposed on a port on the file server to hit via a web browser.

Would running KopiaUI in 'server mode' be what I'm looking for? It seems to be but I would like to confirm before researching it any further. Backups would simply be going to backblaze.
