Is it possible to access elements inside canvas?

Question

JavaScript

There is a site, after authorization, a canvas element appears on it, where there are 2 text fields and one text tag. All the code is minified, and I have no idea how to work with it through js. The question is, is it possible to somehow get the value of these elements through your extension? Let's assume the value of a text tag, or inputs. Ideally, be able to change values ​​in inputs. Is that possible?)

Answer 1

The canvas doesn't have any text tags or inputs, it's just a picture with anything stuck inside or on top.
In any case, you need to look in the code.

Well, nobody canceled the browser console, it will not be difficult to find an input there, and then access it.
