Mutter-rounded is not working with Linux mint 21.2

System

OS: Linux mint 21.2
DE/Desktop-environment: cinnamon

The issue

I was trying to get mutter-rounded to work on my PC. But when i ran ./package.sh in
the directory ~/Downloads/mutter-rounded/ubuntu this was the output:

Supported version: 22.04 21.10
Current version: 21.2
exit.

Cinnamon uses muffin therefore mutter rounded will not work without necessary code changes (which nobody seems to do anyway)
