Would it make sense to refactor the Service enum to a module that can be used by all the notebooks instead of repeated in each of them? I see this being used not just in those 2 notebooks in the future.

We need to unify the way we check for which function to run in all the Python notebooks to match notebooks 10 and 11.
Benefiting from the new services.py module.
