How to uninstall cite2c

[seechew]

I wanted to uninstall cite2c in Jupyter. I did not find any documentation to do that.

If you run jupyter nbextension disable cite2c/main, it won't be loaded. It will still be left on your system - we haven't really thought about a mechanism to uninstall nbextensions - but if it's not loaded, it should have no effect.

This is important, now jupyter-lab has a context menu showing plugins and others you might want to discover similar to VSCode, but with the limitation that there's not way to easily uninstall plugins through a button similar to VSCode where you can install and uninstall plugins at will freely without any hassle.

Maybe this should be put for discussion with jupyter-lab community and maintainers?

For instance in my case I had previously installed cite2c in a conda environment along with jupyter-lab.
Then completely removed that conda env and re-installed everything fresh, jupyter-lab, etc..., but without cite2c.
Now whenever I start jupyter-lab I keep getting the following errors, seems like some config files from cite2c still left on my system.

Any idea how to remove those?
