Parts of the 3d object not showing in the WebXR threejs

I’m facing an issue that is a bit strange. I have an object that I load with troisjs, which is a wrapper for threejs, and render it when it mounts to the XR view.
The thing is that i noticed that some of the 3d objects are defined as objects that may or may not have visible mesh colors. But this object that I load shows only half of it, and the other half is displayed to the data properties when I log them to the console but is not visible. Is there any way to find a work for this thing?
I’m sharing a public repo that I started to work, on and that I’m facing this issue. Feedback is appreciated it
