npub16mtxp68k8c3p2sj0wzhagt3kd8ywkvzlkfyt3vrx9cahzfz000vs8dpnwy (npub16mt…pnwy) you can just build a package and throw that into environment.systemPackages to be included in the system config.

Your package should include the desktop file in share/thumbnailers/*.desktop.
See this link for the files that are linked from environment.systemPackages: https://github.com/NixOS/nixpkgs/blob/0ad13a6833440b8e238947e47bea7f11071dc2b2/nixos/modules/config/system-path.nix#L165
