About the DockKit API in iOS 18

We are experimenting with the DockKit API in iOS 18. However, we are unable to retrieve the speakingConfidence, lookingAtCameraConfidence, and saliencyRank for the person being tracked. We are able to get the rect and identifier. Has anyone been able to retrieve speakingConfidence, lookingAtCameraConfidence, and saliencyRank?
