Debugging jest tests

Hi, I would like to contribute to the jupyterlab and I’m new to it. I’m trying to debug jest test and according to the guideline I should run jlpm test:debug:watch but it doesn’t stop on debugger statement. I prefer to use breakpoints instead but I also don’t know how to run the debugger in vscode in this case since the launch.json is in the sub folder in packages. I wish anyone can help me with this :smile:.
