Python Click Shell Completion

i am currently trying to get a compiled python project which is using click 8.0.4 running with shell_completion.

My project contains multiple downstream scripts, which should support the shell_completion. I am trying to compile this script and make it an executable in /usr/local/bin. Also activating it with

eval "$(_COMPLETE=source_bash main)"

however I get no output here and if i try to test the autocompletion, bash just shows the files of the current directory.

Now my question would be: is this even possible with click/shell_complete in a compiled script? I've tried already a small script where it used to work, however i've now using click.groups and multiple files/scripts and an entry-point.

main.py:

import sys
from commands import cli

def main():
    try:
        cli()
    except Exception as e:
        print(f"An error occurred: {e}")

if __name__ == "__main__":
    main()

commands/__init__.py:

import click
from .config import config
from .deployment import deployment
from .k import k
from .k9s import k9s
from .setup import setup
from .usage import usage

@click.group()
def cli():
    pass

cli.add_command(config)
cli.add_command(deployment)
cli.add_command(k)
cli.add_command(k9s)
cli.add_command(setup)
cli.add_command(usage)

def main():
    cli()

if __name__ == "__main__":
    main()

utils/autocomplete.py:

import click

def runtime_autocomplete(ctx, param, incomplete):
    values = ["TEST1", "TEST2"]
    return [click.shell_complete.CompletionItem(value) for value in values if value.startswith(incomplete)]

commands/setup.py:

from utils.autocomplete import runtime_autocomplete, interaction_autocomplete
@click.option('--runtime', "-r", type=click.Choice(["TEST1", "TEST2"]), required=True, help="Specify the runtime", shell_complete=runtime_autocomplete)
