How to properly Set up "Rigid Body Simulation" for cheaper ragdoll effect?

I’m trying to set up the effect shown in this video: 4.16 Release Notes - Rigid Body Simulation - YouTube

Where the pawns / actors in the level all use this new Rigid body simulation node that’s much cheaper to use.

Can somebody please show me how to properly implement this via screenshot etc… so that I can get the cheap ragdoll effect shown in the video above. It would be really appreciated as I’m trying to optimise aspects of my game right now.

Thanks a ton to anyone who replies!
