How do I add the --version parameter when using click.CommandCollection

[ponponon]

import click

# 定义第一个命令组
@click.group()
def cli1():
    """First command group"""
    pass

@cli1.command()
def hello():
    """Say hello"""
    click.echo('Hello from cli1!')

@cli1.command()
def goodbye():
    """Say goodbye"""
    click.echo('Goodbye from cli1!')

# 定义第二个命令组
@click.group()
def cli2():
    """Second command group"""
    pass

@cli2.command()
def greet():
    """Greet someone"""
    click.echo('Greetings from cli2!')

@cli2.command()
def farewell():
    """Bid farewell"""
    click.echo('Farewell from cli2!')

# 创建一个 CommandCollection，将两个命令组组合在一起
@click.command(cls=click.CommandCollection, sources=[cli1, cli2])
def cli():
    """Top-level command collection"""
    pass

if __name__ == '__main__':
    cli()
