How to change electron.js application code at runtime?

Question

JavaScript

Hello, you need to patch the js and html application code on electone.js in runtime.
Naturally, the question is not about injection dll or WirteProcessMemory, there are no problems with this.
I'm not very familiar with electron, so I don't know where js is stored inside the process. And in general, what process to inject into, because it creates about 10 of them.
Any infa will help, for example, which modules / functions to look at in the electron sorts.

Answer 1

via ajax
or from the file system
but how and why to change someone's application... interesting
