buildPythonApplication with pyqt5 fails to apply theme

Help
1

I am trying to package a python application that uses pyqt5. The application works perfectly, however the dark theme is not applied.

{ lib, pkgs, qt5 }:

let
  drvname = "test";
  python = pkgs.python310;

  pythonRunPackages = with python.pkgs;[
    pyqtgraph
    pyqt5
    tkinter
    click
  ]

  pythonDevPackages = pythonRunPackages ++ [];

  venv = python.withPackages (ps: pythonDevPackages);

  package = python.pkgs.buildPythonApplication {
    pname = "${drvname}";
    format = "pyproject";
    version = "latest";
    propagatedBuildInputs = pythonRunPackages ++ (with python.pkgs; [ setuptools ]);
    src = ./.;
    doCheck = true;
    checkPhase = "pytest";
  };

  apps = python.withPackages (ps: with ps; [ package ]);
in
{
  inherit apps venv;

  shell = pkgs.mkShell {
    buildInputs = [ pkgs.qtcreator apps ] ++ pythonDevPackages;
    shellHook = ''
      export PYTHONPATH="$(pwd)/code:$PYTHONPATH"
    '';
  };
}

I get the following warnings:

I tried all wrapQtAppsHook examples I could find in the manual and in other nixpkgs, however could not get rid of the warning.

Any ideas?
