Python PyQt5 Add Remote Debugging To Compiled Application

Question

In my project I create an application which I then compile with pyinstaller.

The application allows the end-user to add HTML5 files into a folder which the python script then runs as a web app using PyQt5.

During develpment debugging said web app is done by runing the script with the command-line argument --remote-debugging-port=8080 which gives access to the developer tools as a local web page using a Chromium based browser.

However once the application is compiled with pyinstaller these developer tools are no longer available for the end-user. I was trying to use argparse to fix this but it did not work:

if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("--remote-debugging-port=8080")
    parser.parse_args()

    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    app.exec_()

Maybe I'm doing something wrong, how can I add remote debugging to my compiled program?
