Is there a way to generate a js to put directly on whatsapp web page?

Hi everyone!

I'm building a Chrome extension to integrate some functions from whatsapp. I'm trying using the project to generate a js file, is there this option?

My idea is copy the content in the whatsapp web page to use the functions on devtools.
