How to enable Jupyter Lab debugger in arcgispro-py3 virtual environment?

[TylerT]

Hello,

When using stand-alone Jupyter Lab within the arcgispro-py3 virtual environment, what steps do I need to take to enable or turn on the debugger.  Currently the debugger is greyed out, and a hover message reads "Select a kernel that supports debugging to enable debugger". 

The ipykernel is the only kernel I have or will have for the foreseeable future.  The Jupyter Lab documentation states that the ipykernel can be used to debug.  Any pointers would be appreciated.

Thank you,
