I have tried to allow unfree packages to install steam and discord but nothing worked here are some of the things I have tried; 1. { allowUnfree = true; allowUnfreePredicate = pkg: true; }

{ nixpkgs.config.allowUnfree = true; }

( config, pkgs, allow unfree=true)

Every time I tried to rebuild something would go wrong so I tried temporary stuff like NIXPKGS_ALLOW_UNFREE=1 nix-shell And --impure But nothing worked

What should I do???
