How do you get the "document" of the new window ?

Hello, I've been trying to put a listener on the window size but it always get the main window. Does anyone knows how to access the "document" or "window" variable of the new window ? Even document.getElementById() doesn't work in a useLayoutEffect when trying to get a DOM element in that new page. Thanks :)

New window :

NewWindowContent

Hi, you should get the new window object as parameter in the onOpen callback
