Feature Request: NixOS options

[relief-melone]

First of all. Great project. And I am very happy to find betterdiscordctl in the nix repo as well.
One thing though would really improve the nix feeling with betterdiscord. It would be great if one could set the configuration declarative via NixOptions. a nix file could look something like this

{ config, pkgs, ...}:
{
   home-manager.users.johndoe= {
    programs.betterdiscord = {
      enable = true;
     
      customCss = {
        enabled = true;
        real_time_updates = true;
        text = ''
          /* my custom css */
        ''
      };
      
    };
  };
}

is something like this a feature for the future? would also like to contribute but at the moment I am still lacking nix skills to do something like this
