appsim package missing

[kevinmascitti]

The appsim package is missing so the project is not openable if you clone it.
I wanted to open it on unity because I have some problems with the code as my hands are well detected but I don't receive any data in BuildHandSimpleSkeleton method at the following lines:
device.TryGetFeatureValue(InputSubsystem.Extensions.DeviceFeatureUsages.Hand.Confidence, out float confidence); Logger.Instance.LogError(device.name + " " + confidence);
