How do you get the source of a website from a chromium extension?

Question

I want to create an application that can read the values in the HTML and output them in the popup. I am confused, how can I get the HTML source of the website that the user is connected to?

Use a content script to insert a JavaScript file into the page (see here). You can use document.documentElement.innerHTML to access the complete innerHTML of a page. (See also this answer to another question)

That gives me the error "Uncaught TypeError: Cannot read properties of undefined (reading 'innerHTML')" – Olivia Smith May 21 '22 at 22:59
