VR Hand animations

I am quite stuck on how to go about linking my various VR hand animation poses to my BP_Motion Controller. I have managed to create blendspaces and state machines, but I cant get my head around how to link to this to my BP_Motioncontroller to enable input via my Motion controller pawn. In summary, I would like to play different VR hand animation poses but really dont have any reference to go about this. Any information/guidelines would help, especially the key steps to be followed to achieve this.
