Is it possible to create a browser extension that will parse messages from web.whatsapp.com?

Question

Parsing

I have a small electrical company. WhatsApp has several working chats in which shabashki (applications from clients) come in, besides me there are still a lot of masters sitting there. The thought came to mind that it would be cool to receive only those message alerts that contain the word "application" or "coven". Install an extension in the browser that will read messages and, when it finds the right word, will send it to me on telegram

You can do anything. The main thing is that you have enough knowledge and desire. You can also expand (well, or in the order of nonsense - a python scraper), but writing a simple application (on the same electron. Minimum entry threshold) will be more promising ... See WhatsAPP API and do it.
