How can I override/change some parameters in a .desktop file of nixpkg? (lemmy.zip)

I want to edit .desktop files of some nixpkgs for customization, but they are located in /run/current-system/sw/share/applications.. and are readable only.

One possible solution would be to copy them to ~/.local/share/applications but duplicating doesnt sit right with me (this would be my last resort tho).

I would prefer to override the parameters I want to change somehow preferably in my configuration.nix only.

Thanks!

What if I want to append an argument which doesnt already exist? does this also allow to modify multiple lines?

It understands \n if I recall correctly. You can also write regular bash, use templating tools, etc. Just use the nativeBuildInputs parameter if you need a binary that isn't provided by stdenv.
