[Python] add a command to all leaf level commands in a python click chain commands

I have a chain of commands somethig like this.

@click.group()
@click.option('--debug/--no-debug', default=False)
def cli(debug):
click.echo('Debug mode is %s' % ('on' if debug else 'off'))

@cli.command()
def sync1():
click.echo('Syncing 1')
@cli.command()
def sync2():
click.echo('Syncing 1')


tool.py
Usage: tool.py [OPTIONS] COMMAND [ARGS]...

Options:
--debug / --no-debug
--help Show this message and exit.

Commands:
sync1
sync2


This is how I would run my command in a nested fashion.

tool.py sync1 --help

tool.py sync2 --help


now imagine every leaf level command (i.e sync1 and sync2 in this case) calls some API and I want to print the name of that API.

What is the best way to achieve without changing all leaf level function (i.e sync1/sync2).
