Accessing music files on cloud storage (Jottacloud, Music Assistant)

Hi there!

I’ve been searching but found no relevant articles: I have some music stored in a folder on Jottacloud, which I’d like to share with Music Assistant on my Home Assistant.
I didn’t find an integration or an easy way to set up a safe connection.
I did read something about Jotta-CLI, but to me that sounds complex. I just want HA to (read-only) connect to a folder on my Jottacloud.
Any-one cracked this one?
If no simple solution: could anyone point to clear instructions (for dummies ;-)) how to set up a safe connection using Jotta-CLI?
