Can't seem to find the .deb file for os agent amd64

Hi all.
Total noob here so apologies if this has been covered. I did look around extensively for an answer before coming here.

I’m doing my first install ( Mac OS, UTM and Debian 11 (Bullseye) ) and I’m trying to find the .deb file for the amd64 version to install os agent. All the amd64 releases are .tar.gz files. I can uncompress them in Mac OS but the cannot get them into Debian in UTM. I’m sure there’s something I’m missing due to inexperience. Can someone please point me in the right direction?

Thanks very much.
