I’ve just installed the TableOfContents extension for Jupyter Lab. I have Version 0.35.3 of Jupyter lab.

And here is some more information about the configuration:  
jupyter --version  
4.4.0

jupyter notebook --version  
5.7.4

Where can I find the option to activate the Cell toolbar such that I can add tags?

I think you want this one: [https://github.com/jupyterlab/jupyterlab-celltags](https://github.com/jupyterlab/jupyterlab-celltags)

I still haven’t figured out how to list extensions and quickly install them from within jupyterlab so I usually just manually install them
