USD Asset animated. Animated 3D Models.

I have animated USD assets and when I upload them to FAB they can’t be processed?
FAB allows animated objects that are not FBX?
As far as I know, FBX only allows animation of transformations but does not allow movement of vertices, as ABC and USD do.
Sketchfab allowed animated Alembic files.
What can be done to upload animated 3D models?
