I'm trying to implement the script for ML1 to recognize gestures and I followed the examples provided in the SDK documentation. When I try to run the project, Unity says that '_The type or namespace name 'InputSubsystem' could not be found (are you missing a using directive or an assembly reference?)_'. If I understand correctly, the InputSubsystem should be available when you have the following using statement:

using UnityEngine.XR.MagicLeap;

I also have following using statements that I took from [documentation](https://developer-docs.magicleap.cloud/docs/guides/unity/input/gesture-classification/unity-gesture-classification-api):

using InputDevice = UnityEngine.XR.InputDevice;  
using HandGestures = InputSubsystem.Extensions.DeviceFeatureUsages.HandGesture;  
using GestureClassification = InputSubsystem.Extensions.MLGestureClassification;

I don't understand why it doesn't work. Am I missing something?

Environment: Lumin SDK - 0.26.0  
Magic Leap 1 - 0.98.30 OS  
Unity - 2020.3  
API Level - 10  
Windows 10
