.ipynb file in Microsoft Teams not opening collaborative editing

I know Jupyter is not exactly designed as part of Microsoft Teams, but as many people work at an organisation that ‘lives’ in Teams this would be very interesting.
Even half-solutions or workarounds would be a valuable step.
Any suggestions?

I’ve no idea how opening a document from Teams gets sent to a Jupyter server, but if it’s one running with jupyter-collaboration, it should Just Work, I would think…
