I have a similar issue: how to install maven package in the notebook when running with  a serverless cluster?

I need to install com.crealytics:spark-excel_2.12:3.4.2_0.20.3 in the notebook like the way pypl libraries installed in the notebook. e.g. %pip install package_name for pypl libraries.

I don't want to use environment sidebar and dependencies. First of all, adding the maven package in dependencies did not work ( I am guessing because it's not Pypl library). Secondly, I will be running the notebook in a workflow via Git, and even if applying the library via dependencies tab worked, it would not know about it when running the notebook from Git, so would not work.
