How to enable Spatial Awareness on Android?

[XRAdventure]

Hi, I am trying to replicate your show case WebXR on Android with MRTK.

I want to enable Spatial Awareness like this.

But, I am not able to do it.
I enabled it in MTRK ToolKit. But it doesn't work,

What should I do to activate it?
My current set up:
Unity 2019.4.23
MRTK 2.7
Android 8

Thank you for your help

Hey,
This demo was a test before I developed SimpleWebXR : https://github.com/Rufus31415/MixedRealityToolkit-Unity-WebXR

In fact, a hack with Three JS allows to visualize spatial meshes, it implements the old spatial mesh API : https://github.com/Rufus31415/MixedRealityToolkit-Unity-WebXR/blob/1bf7748024ae2ee619828fad6b4cbc25e01cba4e/Assets/WebGLTemplates/WebXR/index.html#L145

But SimpleWebXR does not implement yet the new spatial mesh API
