Communicate with the webview of the reader

[alxh0610]

Hi, at the moment I'm trying to fully understand the architecture as I'm fairly new to these kind of projects. In order to learn to work with such code I was wondering where I would need to start to work with the webview the ebook is rendered in (maybe to include some kind of feature, play around a little). As far as I'm aware the dom.js creates the webview in the viewport container (this function is called in the Reader.tsx file) so that's where I need to look at?
I didn't file this as an issue because I do not think I can contribute anything very useful, it is mainly just me trying to understand a professional project better.
I would really appreciate any advice!
