[Python] How to activate only options when we use click.group()

I'm currently working to create Command line arguments with click. I almost done the research, and everything is working fine. The issue is I want to use the only option while working with the click.group() other than sub commands.

Lets say myCommand --version this should print my application's version but it's raising error saying Error: Missing command.

My code is:

import sys
import os as _os
import click
import logging

from myApp import __version__

@click.group()
@click.option('--version', is_flag=True, help="Displays project version")
@click.pass_context
def cli(context, version: bool):
if version:
print(__version__)

@cli.command()
@click.pass_context
def init(context):
click.echo(message="Starting initilization for the project" + str(context.obj))

@cli.command()
@click.pass_context
def install(context):
click.echo(message="Starting installing from the saved data")


Here --version is only working when I call the command with option like cli --version init, But I want this to be cli --version to print the version.

Can anyone help me with this?
