How to block applications from accessing the Internet (lemm.ee)

So I often have to install and test different programs. I do not want programs to access the Internet immediately. After a while I might want to allow it, so it should be easy to allow or disallow internet access at the application level.

Basically I wonder if there is an easy way to do this. It seems that OpenSnitch can do this, but it doesn't seem to work on OpenSuse. I might be able to get it to work eventually, but before I spend hours tinkering with it, do you know of a better solution? Might this even be possible with the built-in firewall or AppArmor?

Heres my lazy and probably stupid way (im a nub btw)

Only install flatpak apps.
Install flatseal and manage every app using that.

Cons: might be a problem to manage if you got like 1000+ flatpak apps installed
