Debugging a function being called from notebook in jupyter-lab

I have a notebook in jupyter-lab, lets say it is as simple as this:

import importlib
import data_exploration as de
importlib.reload(de)
de.test(3,5)

In the data_exploration.py file I have the following function:

def test(a,b):
    c=a+b
    d=a-b
    return c,d

I am able to set a breakpoint in the .py file, but when I run the code from the notebook the execution doesn't stop at the breakpoint. How can I connect the debugger in the notebook and in the source file. Please also see the attached images:
