Help: yunohost with usenet

Hi folks, I have yunohost up and going on an old Lenovo desktop - works great and was really easy to get operational. Jellyfin is working and I've manually dumped in some media to test it out.

On another windows machine, I have SABnzbd working and have been able to get some media.

And here's where I'm stuck. How do I get a Usenet client on yunohost? SABnzbd isn't a yunohost app, and I can't find another client in the app list. I've tried and failed to point sonarr at SABnzbd on the other computer, but I wouldn't want that as a longterm solution anyway. Is it possible to apt-get install SAB on yunohost? It's just debian afterall. Seems risky.

Any help would be greatly appreciated 👍
