Hi, thanks for the great app! I have made a pop.nix script which correctly installs pop on nixos and runs it through steam-run. I'd love to see it on nix packages, but I'm not ready to maintain it. So I'm attaching it here in case somebody will be searching for it and in case the devs would take on the support. Here's the script: https://gist.github.com/licht1stein/0eaf44003088ae3dbbfcf55481d14b7d
