How to use PhysX in repo.bat Composer

Now that the Composer launcher is deprecated and PhysX menus are deprecated and Blender extension is Deprecated etc.
How do you get Physx to work in a repo.bat build / launch kit? I have every single Omni Physics and PhysX and Sim tool I can find enabled and still there are no options for windows or create tools allowing simulations. Not one page of documentation from official or community tutorial, video, etc. has matched what content I see in my composer with what is being shown in technical write ups screen shots or recordings. Do I need to run a cmd line to install a new layer? Are all the tools just removed and waiting to be rebuilt? NVIDIA Champions AI but even that is beyond confused on how to help solve this as its all trained on out dated info leaving LLMs confused as to why their confident instructions fail.
