Refactor into Module

Help
1

I have a flake where my mac uses home manager modules in a darwin config. I am stuck on how to refactor the “home-manager.darwinModules.home-manager” inline module fully into a separate file (./home/jeffwindsor.nix). I would like to have a modules list that looks like this:

      modules = [
        ./home/jeffwindsor.nix
        ./machine/macbook_m.nix
        ./desktop/aqua.nix 
        mac-app
      ];

but I seem to not grasp how to accomplish this. Any help is very much appreciated.

My current config:
flake.nix

{
  description = "jeff.windsor";
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    nix-darwin = {
      url = "github:LnL7/nix-darwin";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    mac-app-util.url = "github:hraban/mac-app-util";
  };

  outputs = inputs:
  let
    ds = inputs.nix-darwin.lib.darwinSystem;
    home = inputs.home-manager.darwinModules.home-manager;
    mac-app = inputs.mac-app-util.darwinModules.default;
  in
  {
    darwinConfigurations."Midnight-Air" = ds {
      modules = [
        home {
          users.users.jeffwindsor = {
            name = "Jeff Windsor";
            home = "/Users/jeffwindsor";
          };
          home-manager.users.jeffwindsor = import ./home/jeffwindsor.nix;
        }
        ./machine/macbook_m.nix
        ./desktop/aqua.nix 
        mac-app        
      ];
    };    
  };
}

separate file

{ ... }: {
  imports = [ ./module/eza.nix ];
  home.shell = {
    enableZshIntegration = true;
    enableNushellIntegration = true;
  };
  home.stateVersion = "25.05";
}
