Add a python package to a PySide6 QtCreator project by .whl file

I have a custom python package that I created it is stored inside a .whl file and I would like to use it in my PySide6 QtCreator project; this package is only useful to me and I don't want to gum up PyPi with things that nobody else will ever use. I would like use this package in my project, but I don't know how to include my package in the project, or even install the package to the venv. My project will depend on the package, and I would also like it to be distributed with the qt project whenever I share the code with anyone else. What is the recommended/default way to do this or is there even a recommended way to do this in the first place?

Update: is it possible to commit the whl file to the repository and then include it in the requirements file? If so it will work decently well with QtCreator.

I looked into it, and it turns out that I can commit my .whl file to the repository, and then add it to the requirements.txt file. After this I click the Build button

and the .whl file will automatically be installed and used in the pyside project from now on. The .whl file doesn't appear in the file browser for QtCreator, but if I use the terminal, I can add it to the repo. I can't install it using pip in the terminal, because the terminal can't access the venv, that is why I have to use the build button.
