An XRSession object indicating which WebXR session the event refers to.
In this example, the session property is used to obtain the session object to manage when an event is received.
xrSession.addEventListener("visibilitychange", (e) => {
switch (e.session.visibilityState) {
case "hidden":
myEnableRendering(true);
break;
case "visible":
case "visible-blurred":
myEnableRendering(false);
break;
}
});
