Need help packaging a smartcard application

Help
1

So for my work i need to use a program from secmaker.com for authentication with smart-card. I tried to package the program for nix but i have not fully succeeded. I have managed to get the program to start but when i launch the application the GUI loads with a empty page and this is printed to the console Could not determine the accessibility bus address

Any help in this area would be much appreciated.

netidapp.nix

let
  netid = pkgs.stdenv.mkDerivation {
    name = "netid";
    src = pkgs.fetchurl {
      url = "https://service.secmaker.com/access/download/SecMaker/7.1.2.009/NetiDAccessSetup_linux64.tar.gz";
      sha256 = "sha256-RiMXUPuKJaoYIQBTw0Tk0csBXrzodOEikyyviK33En8=";
