I need help creating an app using external ./python.sh

I’m creating an app following the example of the (kit-project-template), and I’m unsure how to incorporate the ./python.sh script located in the Isaac Sim folder into my app. This script is what I use to run my Python file for simulations involving ROS2. Any tips on how to do this?

I can launch Isaac Sim from ROS 2 App.
You can see the sample in following repository.

I hope this is helpful.
