I have a .stl in “Standard Tesselated Geometry File Format” - how do I get this into a format which VisionOS can use?

Notes:

double-clicking on the .stl launches Xcode and shows the Scene graph
I’ve added it to a template VisionOS app. It comes in with a gray icon that is otherwise identical to the blue icon that the template creates (named “Scene”) - but I cannot figure out how to get the model contained in the .stl to be recognized.
Reality Composer Pro will not open the .stl file

Many thanks!

Can Apple's Reality Converter convert the .stl file to .usdz? (I don't think the old version could)

On occasion, I've imported models into Blender, exported them as GLTF files, and then used Reality Converter to convert them to USDZ.

One issue I've run into in this process is the unit size. For example, in Reality Converter, I will change the unit size from meter to centimeter and then back to meter and then export from Reality Converter. For some reason, this solves the problem of a model appearing at 1/100 the size you expect.
