Someone using BreezeStyleSheets with PyQt6 here? How to?

Question

Using PyQt6 on Python-3.11. Coding with pycharm.

Have some problem with understanding how to use Alexhuszagh's BreezeStyleSheets - https://github.com/Alexhuszagh/BreezeStyleSheets

I downloaded full code as a zip, then placed folder from the archive inside my project folder, full path for folder is like D:\My\Project\BreezeStyleSheets and all that assets, dist, etc. folders inside.

Then I'm going to this part: https://github.com/Alexhuszagh/BreezeStyleSheets#pyqt6-installation

I created an empty test.py file inside the project (it is on one level with BreezeStyleSheets folder) and placed there:

from setuptools import setup

setup(
    # Either option is valid here.
    #   Either use `package_data` with enumerating the values, or
    #   set `include_package_data=True`.
    # include_package_data=True,
    package_data={
        "breeze_theme": ["BreezeStyleSheets/dist/pyqt6/*"],
    },
    zip_safe=False,
)

And it crashes with:

usage: test.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: test.py --help [cmd1 cmd2 ...]
   or: test.py --help-commands
   or: test.py cmd --help

error: no commands supplied

Where I'm incorrect in what I'm doing?

PS I tried commenting include_package_data or package_data rows, nothing changed.

Update1: TY for help, I tried it and find that it's not that what I want to.
