Basic: How to play skeletal mesh animation from separate blueprint?

Just started importing animations into Unreal. I’m sure this is really simple, but I haven’t been able to find the info I need (probably because I don’t know what terms to use to find it).

I have a door that’s been imported as a skeletal mesh with an ‘open’ animation. I want to use a separate box-collision blueprint to open the door. I want to know the most efficient way to do this. Do I need to set up a separate BP for the door, or can I somehow call the animation from the collusion BP?

Sorry if this is basic stuff. Do you know of a tutorial that will help?
