Cannot create a SharedArrayBuffer

[pflannery]

Details about the bug:

• Web browser and version: Edge 108.0.1462.54
• Operating System: Windows
• Steps to reproduce this: https://editor.p5js.org/pflannery/sketches/RwHhvso2I

When trying to create a SharedArrayBuffer an error message is displayed

SharedArrayBuffer is not defined

In order to enable SharedArrayBuffer the server needs the following headers:

• Cross-Origin-Opener-Policy with "same-origin" (protects your origin from attackers)
• Cross-Origin-Embedder-Policy with "require-corp" (protects victims from your origin)

We need to think more about where we set those headers, which honestly I haven’t so I don’t know the answer. Do we need it on the entire server?

The sketch itself is run in an iframe. Do we need to add anything to the handler which serves the iframe? Is that included in the server.js file or is it elsewhere? The iframe is served from a different subdomain. Is that considered “same-origin” or not? Do we need to explicitly allow that subdomain as an origin?

edit: I think the file which needs changes is this one?

TBH I haven't properly reviewed @soniyaprasad77's code. Maybe you can start by looking at that, and investigating the questions in my last comment. We may need a team effort here!

I have implemented the suggested modifications in both codes , but the issue persists, and errors continue to occur.

If you could offer any additional solutions related to this issue, it would be helpful.
