How to get selected text in pdf via JS?

Question

JavaScript

Hello everyone, the situation is this:

there is a page, a pdf file is loaded onto it through <embed>or <iframe>, you can select text there, the pdf itself is displayed fine, but window.getSelection() does not work. I googled this question - it turned out that this can not be done, tk. thus, another page of another "window" is loaded through iframe or embed, can someone come across a similar one, how can I get this selected text from a window with pdf?

Answer 1

Maybe something like this?

document.querySelector("iframe").window.getSelection*(
