New to Mint - How to determine software compatibility? - eviltoast

Hi there, I started using Linux Mint Cinnamon a few days ago and am currently setting up my workspace, that includes software I can’t find through the integrated Software Manager

My biggest issue is that I don’t understand how to determine if software is compatible with Mint. Often devs declare their product to be compatible with ubuntu. Since Linux Mint is based on ubuntu, does that make the software automatically compatible?
