Hey thanks for you comment.
The Ray-Tracing Extension is currently only available for Windows and Linux.
My next plan is to implement the extension into Dawn's D3D12 backend, so I can build chromium with my Dawn fork and have Ray-Tracing available directly in the browser (at least for myself) :)
Wow, very impressive! I believe this is only available for MacOS Chrome Canary, with enable-unsafe-webgpu flags toggled on. But we are starting to see more example code.

This is the first specific RTX target engine I've seen so far though. Starting to feel like the future with full time real-time hardware rendering capabilities in the browser ;)
Do you mind my asking what you plan to build with it?
