Followed the instructions in this installation guide - https://github.com/mathworks/jupyter-matlab-proxy - to install the jupyter-matlab-proxy in the jupyterhub python environment using command

sudo /opt/jupyterhub/bin/python3 -m pip install jupyter-matlab-proxy

But upon first execution I have to provide Mathworks accounts details.

The license on Chimay belongs to Prof. Jon. So, he'll have to insert those.

Right now MATLAB kernels for jupyter notebook as well as console show up (as shown in screenshot below) but code will not execute.

If I click on Open MATLAB tab, it will ask for Mathworks account login details.

The installation guide mentioned above says,
"When you execute MATLAB code in a notebook for the first time, enter your MATLAB license information in the dialog box that appears. See Licensing for details. The MATLAB session can take a few minutes to start."

Follow-up with Prof. Jon needed.
