Incomplete or Broken setup?

[git2212]

Having a fun time with this plugins lol...
I have VS-Code server setup i docker container and since it's been running great... I figured why not add Jupyter notebook support... so installed the plugin pack ... no errors... opened up a new notebook... created a new venv ... it installed all the jupyter stuff automatically and then... selected it as the 'kernel'... no errors anywhere to be seen... in the 'ports' tab I see a jupyer server instance is spun up with a port forward...
... when I try to add either a code or a markdown cell via the UI ("+Markdown", "+Code" buttons) nothing is happening... no errors, no new cells, nada... without errors not sure which direction to go lol... perhaps I missed an install/config step?
