Not working on Debian Buster (.deb and .AppImage)

[starfetch]

I tried to get the Music Assistant Companion v0.0.22 (great piece of software, btw!) to run on a Debian Buster machine. With the .deb package, it installs (seemingly) fine with apt install, but trying to run it with music-assistant-companion (a recognised command), results in the following error:

music-assistant-companion: error while loading shared libraries: libssl.so.3: 
cannot open shared object file: No such file or directory

Trying the .AppImage, after making it executable, results in the following error(s):

Searching for the error very briefly led me to this stack answer, which cautions against updating these dependencies, since a lot of the OS depends on it.

Can I therefore assume, that I am simply out of luck on my old Buster machine? I could not find requirements in the README, therefore the issue.

Happy to provide more system info if needed, and also to close the issue as a wontfix if it is simply my setup being too old.
