Pretty sure this is wrong, and you actually meant to use the embedder-policy header, not the resource-policy header.

Adds the required headers to load Hubs in a secure context to access SharedArrayBuffers and high resolution timers. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/SharedArrayBuffer#security_requirements. This also increases security in general, but will make it more difficult to communicate with iframed hubs clients if that becomes necessary in the future.
