HandSkeleton.Joint transform when isTracked = false

Hello there,

Do you know what happens if I call one of the following but the Joint is not tracked?

var anchorFromJointTransform: simd_float4x4 The position and orientation of this joint relative to the base joint of the skeleton.

var parentFromJointTransform: simd_float4x4 The transform from the joint to its parent joint’s coordinate system.
