Question Gestures in HoloLens/Magic Leap using AR Foundation/XR Interaction Toolkit

Hi! I'm trying to create a cross-platform application for HoloLens 1, HoloLens 2 and Magic Leap using:
- AR Foundation 4.1.0-preview.6
- XR Interaction Toolkit 0.9.4
- Magic Leap XR Plugin 6.0.0
- Windows XR Plugin 4.0.2

Questions I have:

• How do I add gestures for Hololens & Magic Leap using AR Foundation and/or XR Interaction Toolkit? (<- is this the right toolkit for this?)
  
  
• From the Magic Leap XR and Windows XR documentation there seems to be a WindowsMRGestures and a MagicLeapGestures component. Do I need those? if so, where do I attach these scripts to?
  
  
• Do I have to follow the gesture/hand input tutorials from Microsoft/MRTK and Magic Leap's site instead of using AR gesture interactor (XR Interaction Toolkit)? I don't think I can deploy it to all 3 platforms this way but maybe I'm wrong.

What I've tried and/or read so far is:

• Followed this tutorial:
  
  Even though it's for ARcore/ARkit, I thought -since AR Foundation supports multi devices- it'd work for HL/ML as well, it didn't And I couldn't find tutorials specifically for HL/ML in combination with AR Foundation.
  
• Build+deployed the AR Example scene of the XR Interaction Toolkit on Hololens 2: https://github.com/Unity-Technologies/XR-Interaction-Toolkit-Examples
• Build+deployed the 'Interaction' sample scene from AR Foundation: https://github.com/Unity-Technologi...tree/latest-preview/Assets/Scenes/Interaction
• Followed this tutorial:
  
  Couldn't really apply the VR setup to AR.
  
• XR Interaction Toolkit documentation (starting from 'AR Gestures'): https://docs.unity3d.com/Packages/com.unity.xr.interaction.toolkit@0.9/manual/index.html
• AR Foundation documentation: https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@4.1/manual/index.html
  
• Magic Leap XR/Windows XR documentation:
  https://docs.unity3d.com/Packages/com.unity.xr.magicleap@6.0/manual/index.html
  https://docs.unity3d.com/Packages/com.unity.xr.windowsmr@4.0/manual/index.html
• Gestures in MRTK's documentation: https://microsoft.github.io/MixedRealityToolkit-Unity/Documentation/Input/Gestures.html
• Hand Input from Magic Leap's Developer page: https://developer.magicleap.com/en-us/learn/guides/hand-input-unity

Any help/advice/suggestions are appreciated! Thanks for reading.

 

Bump. I am looking for something like a `XRGestureInteractor`, similar to the `ARGestureInteractor` that unfortunately only seems to apply to touchscreen gestures.
