Dynamically adding cli commands

I am just getting started with the library Typer for building CLI's. There are too many commands in my cli.py and I moved them to a separate folder “commands”, but I cannot figure out how to implement a dynamic loader for these commands in cli.py.

my_app/
 __init__.py
 commands/
     __init__.py
     command1.py
     command2.py
 cli.py

I started by creating a class "Command" for each command from module "commands" with a single function "handle (** options)" that contains the functionality. Ideally, when starting cli.py, I want to check which modules are there and load them dynamically, leaving the cli.py file clean. But I do not understand at all how it is better and more correct to implement it.
