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.
