Backup "Uptime Kuma" for migration to another host

Hi all,

I would like to backup my data from Uptime Kuma addon such that I can import that backup on a different machine (I want to host Kuma on a separate docker server).

I have not found any way to do this. I don’t have SSH access to my HAOS. The terminal addon does not know the docker command, so I cannot get the data directly.

Any recommendation/idea what I could do here?
