How to access state blend weight

Hi, I am looking at HeroTPP_AnimBlueprint from the ShooterGame example, and I stumbled accross the node “NewStateMachine.JumpLoopState-> Blend Weight” that they have in the top left. I would like to know how to get that node - I can’t find it when I start typing, dragging the state from the AnimationGraph panel doesn’t work either. The only node I am able to find is StateWeight(JumpLoop), which I guess might return the same thing, maybe node in the picture is deprecated so I can’t find it? Moreover, I would like to know why and when this is useful, as I haven’t found this anywhere else.
