Activate Particle System on movement

So total UE4 noob here, I am trying to make a VR game while learning some stuff about UE, but I can’t figure this one out

What I want it to do is get this trail (the fire trail from advanced magic FX 12) behind my sword when I am moving it in VR, but I can’t figure out how to actually do this and get it working

any help is welcome.
