Isaac Sim: Particles cannot move with clothes!

When Isaac Sim uses code to import clothes saved in USD format and use code to add particle cloth properties to the clothes, I find that the particles cannot move with the shell of the clothes. Can someone please explain what the problem is? I personally think it is a basic problem, such as some omissions when the code is imported into the world.

This is the code I used to introduce a garment into the stage.
