Hello,

I was trying to install several extensions (e.g. @jupyterlab/toc-extension, @jupyterlab/debugger, @jupyterlab/apputils) but I ran into some issues:

1. I got an "extension installation error", where it tells me to upgrade to a newer version of JupyterLab (my current version seems to be 3.2.0). 2. I was asked to rebuild ("A build is needed to include the latest changes") JupiterLab.

Could I get the manager role to be able to rebuild JupyterLab to install extensions? Is it possible for me to upgrade to a newer version of JupyterLab?

I've also got some questions unrelated to the problems above: Would you recommend using JupyterLab in combination with Coscine (https://coscine.rwth-aachen.de/)? If I'm working with industry data, which is not meant to be shared with other people, would it be ok to use JupyterLab? In other words: Where and in what form is data saved in JupyterLab?

Looking forward to your answers!

Kind regards, Jakob Lötfering
