How to add a debugger statement inside a node module?

[pmrotule]

With Yarn v1, I'm used to add debugger statements inside the distribution assets of the installed package inside node_modules in order to use Node.js DevTools in Chrome. Now that the code are inside a .zip file within .yarn/cache, I have no idea how to do that. It's pretty much the issue described here: https://youtrack.jetbrains.com/issue/WEB-45273

I use VSCode, but I don't use it its debug feature or integrated terminal. I use a good old terminal in Mac.

Anyone could help me figure this out?
