The HTTP Permissions-Policy header idle-detection directive controls whether the current document is allowed to use the Idle Detection API to detect when users are interacting with their devices, for example to report "available"/"away" status in chat applications.

Specifically, where a defined policy blocks use of this feature, IdleDetector.start() calls will return a Promise that rejects with a DOMException of type NotAllowedError.
