Add Skeletal Mesh Component - No Simulate Physic - Bug

In Version 4.19 and 4.20.

I want to spawn a skeletal mesh and simulate it physically. It does not work with these nodes. Simulate Physics does not work on AddSkeletalMeshComponent.

What is the type of Mesh? Static Mesh or Skeletal Mesh? I am asking this because I want to know where this Physics Asset Override comes from.
