Clarification on USD export format from Blender for real-time SMPL control in Isaac Sim #1

Hi,
First of all thank you for the great tutorial and for providing the ready-to-use Animation Graph and Pose-Provider variables.
I would like to replicate the workflow, but starting from my own SMPL-X model in Blender 4.5:

What USD variant (binary/usdc, ascii/usda, usdz) and what export settings (armature, shape-keys, modifiers, etc.) should be used when exporting from Blender so that the skeleton, skin-weights and Animation prim are compatible with the graph shown in the tutorial?

Once the file is loaded in Isaac Sim, is it currently possible to drive the character in real-time (e.g. streaming pose parameters every frame) through the same character.set_variable("poses", trans) and character.set_variable("rots", quats) interface, or are there additional conversion/baking steps required?

Any hints or a mini-checklist would be highly appreciated.
Thanks in advance for your help!
