Is there a way to log out using jupyterlab?

Dear All,
I installed jupyterhub for a university provided research compute machine, and configured to have jupyterlab as my default editor. I noted that if I were to use a /?tree (a jupyter notebook as opposed to a jupyter lab) instead, I could see a logout button on the browser and a control panel on the top right hand corner.
Using a jupyterlab, how do I log out of a session?
Would greatly appreciate some guidance.

I think is the extension to install for that. It adds some/all of the buttons you get in the normal Jupyter notebook UI when you are on a JupyterHub for logout and admin things.
