Resolved AR Foundation what happens when ARSession loose tracking???

Hello, what happens when ARSession loose tracking??

How to know objects location in space when you cover up camera?
What happens to the world position when tracking state is limited?
I need to know objects position/rotation after camera is covered, but debug log says that it`s the same position but actually is not, probalbly the whole world is rotated after you cover up camera, can anybody advise how to know the exact object location?
Thank you.

In AR Session there is a code snippet :

ARSession.cs

void Update () {
if (subsystem != null && subsystem.running) {
if (m_MatchFrameRate && descriptor.supportsMatchFrameRate) {
Application.targetFrameRate = subsystem.frameRate;
QualitySettings.vSyncCount = 0;
}

subsystem.Update (new XRSessionUpdateParams {
screenOrientation = Screen.orientation,
screenDimensions = new Vector2Int (Screen.width, Screen.height)
});

switch (subsystem.trackingState) {
case TrackingState.None:
case TrackingState.Limited:
state = ARSessionState.SessionInitializing;
TrackingStateNotification.text = "LIMITED";
break;
case TrackingState.Tracking:
state = ARSessionState.SessionTracking;
TrackingStateNotification.text = "TRACKING";
break;

}
}
}
