How to compile Angular on Heroku side?

Question

Python

I have a Flask project for the backend and Angular for the frontend
. The whole thing is running on Heroku. On Heroku, this works like a regular python project that already has a compiled (using ng build --prod) js bundle in its static resources. JS is built accordingly on the local machine before deploying to heroku.
How can I make it build on the Heroku side after deployment. I mean how to run ng build --prod on heroku side for python project.
