How to test how much memory/processor time a particular library consumes inside an angular application?

Question

JavaScript

Hello.
Given: An Angular application inside which uses a lib based on RxJS. I have a suspicion that this lib is spending resources too uneconomically. How can I test how much this particular library consumes resources? Not a browser tab and not the entire application, but specifically this library?

On the performance tab in chrome dev tools, you can see how long a particular piece of code is running, on the memory tab, you can take snapshots, there will also be statistics for each type of object
