How do I get the "apply Physics animation profile" node to activate?

I’m experimenting with the physics animation thing in the mannequin mesh and I figured in order to solve a problem, I should make some bones in an animation profile flimsier than others.

I feel like this node is supposed to activate the desired profile for that mannequin but I can’t get it to work for some reason. Can you please help me? Tell me what I’m doing wrong?

Is it because you aren’t specifying which “Body” to apply the settings below? The “Body Name” needs a bone name.
