How to go from mapped source to minified code

I need to find where a specific function in main.js.map is in the minified code main.js.

I tried to do it in Chrome dev tools, but that does not seem possible. Chrome directs me to the entire minified file, not to a specific location in the minified file.

I saw a method involving break points, but that would not work for my use case

I am happy to do it manually, with less, but I’m not sure how to do it.

Any pointer?
