How do i trigger a fbx animation with box/volume trigger?

Hey I have only just started using unreal so apologies for such a noob question.
I’m trying to activate a fbx animation for a bridge (you walk towards the gap between two platforms and the bridge builds itself) Iv tried a box and volume trigger in blueprints using a OnConponentBeginOverlap and OnConponentEndOverlap to activate it but I can’t figure out how to a) find the correct function node to play the animation or b) create it’s own function to play the animation. I came across the attached solution online Is it possible to play animations with triggers? - Character & Animation - Unreal Engine Forums

but I’m confused by the play animation and set animation nodes. Can anyone shed any light on this as I plan on importing a lot of more complicated animations into Unreal in the future and this issue is likely to come up all the time.
