Multi Canvas , Multi Camera , One Scene

There are 2 canvas elements in the html file I created, 1. I created a single scene on the canvas and put 2 different cameras. The image of the camera is projected onto the 1st canvas. How do I reflect the data of the 2nd camera to the 2nd canvas?
Note: English is not my native language.

I believe this documentation may help - Using Multiple Canvases | Babylon.js Documentation
Example - Babylon.js - Multi views demo

Yes I have read this design and documentation, but when I add the lines shown in this demo engine.registerView(document.getElementById(“renderCanvas1”), camera1);
interface freezes and crashes.

Are there any errors on your console?
