AGOL Notebooks debugging

I would like to debug my AGOL notebook, as I am trying to create my first custom web tool. I have created a very simple notebook:

from arcgis.gis import GIS
gis = GIS("home")

print('print this')

After publishing, I add it to an ExB app as a custom Analysis tool. When I run it, the code takes over a minute to run, but says it is successful. However, what I want is to debug my tool using Chrome Developer tools. If I inspect the Chrome console, I see no messages. Is there a video or tutorial on how to debug an AGOL custom tool? I was actually working on some tools some months ago and got pulled away. I could swear that it was working at that time! Any suggestions on debugging are welcome.
