from @mrocklin :

I wonder there is a way to get this YouTube video in a JupyterLab pane when the user starts up their session. Any suggestions @ian-r-rose?

It should be possible -- the help panels are just iframes on the page, and those are serialized in workspace files. If you open a help panel, save the workspace, and manually replace the url in the workspace JSON with the youtube embed link, it should do the job.
