Apple Reality Composer: Import tracking object

Hi there,

Just wondering if anyone knows what file types can I use to use a tracking object? It seems that both OBJs and USDZ files both are not support. Can you only import scans? If this is the case, is there a more precise way to scan the 3D model I have. A really odd thought but may be a piece of software that converts my model into a supported scan file?

I have CAD model of the item I am trying to track as I have 3D printed the object
