I'm trying to distribute my Python package across operating systems using Briefcase (following the official BeeWare tutorial), but I'm more familiar with using Poetry for package management. I found a tutorial that combines the two tools, but when executing the final command poetry run python setup.py linux -s, I get the error: error: invalid command 'linux'.

Here's the code for the setup() function in my setup.py:

setup(
    name=<my-details>, # Personal details omitted here
    version=version,
    description=<my-details>,
    long_description=long_description,
    author=<my-details>,
    author_email=<my-details>,
    license='BSD license',
    packages=find_packages(
        exclude=[
            'docs',
            'tests',
            'windows',
            'macOS',
            'linux',
            'iOS',
            'android',
            'django'
        ]
    ),
    classifiers=[
        'Development Status :: 1 - Planning',
        'License :: OSI Approved :: BSD license',
    ],
    install_requires=[
    ],
    options={
        'app': {
            'formal_name': <my-details>,
            'bundle': 'com.example'
        },
        # Desktop/laptop deployments
        'macos': {
            'app_requires': [
                'toga-cocoa==0.3.0.dev15',
            ]
        },
        'linux': {
            'app_requires': [
                'toga-gtk==0.3.0.dev15',
            ]
        },
        'windows': {
            'app_requires': [
                'toga-winforms==0.3.0.dev15',
            ]
        },
        # Mobile deployments
        'ios': {
            'app_requires': [
                'toga-ios==0.3.0.dev15',
            ]
        },
        'android': {
            'app_requires': [
                'toga-android==0.3.0.dev15',
            ]
        },
        # Web deployments
        'django': {
            'app_requires': [
                'toga-django==0.3.0.dev15',
            ]
        },
    }
)

I've looked up the purpose of the options parameter, but only found this brief description: "A dictionary providing the default options for the setup script." According to the tutorial, running that command should open a blank window (which works when I use Briefcase directly following the BeeWare tutorial). Since I prefer using Poetry as my primary package manager, I want to understand:

1. The working mechanism and specific role of the options parameter
2. How to properly configure this parameter to fix the current error, make the command work as expected, and open the blank window
