This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The onvisibilitychange attribute of the XRSession object is the event handler for the visibilitychange event, which is dispatched when the visibility state of the XR session changes. The visibility state of the session is accessible via XRSession.visibilityState.

Note: The visibility state of XR session affects the frame loop so callbacks registered via XRSession.requestAnimationFrame() might not be called. Consult XRSession.visibilityState article for details.

Syntax
