Unsolved Pickable model with QQuick3DGeometry

[Sieve]

Hello.

Does anybody have any experience or knowledge about picking a model with a custom geometry?

Currently I have a custom geometry which I generate using QQuick3DGeometry class as described here.
Everything is working as expected except the model picking.
A simple test with the model below is producing results as expected, so the View3D and MouseArea configurations are fine.

Model {
            source: "#Sphere"
            pickable: true
            materials: [
                ...
            ]
        }

Any information you can provide me would be greatly appreciated.
