Oculus Plugin Content - Oculus RiftS Controller - Roughness Mask not connected in material

New Material for the new RiftS/Quest controller meshes does not have roughness mask connected.

With roughness connected controller looks better (Shiny buttons, Matte Grip) but I want to call out a crooked mask next to grips.

1. Enable 'Show Plugin Content' in Content Browser and navigate to 'OculusVR Content'
2. Open "OculusTouchForQuestAndRiftS" material
3. Observe that the assigned texture contains a roughness map in Alpha Channel that is unconnected.
