How to make a Variable in a Blueprint Accessible in other Blueprint

Essentially, the problem I’m running into is that I want to have an actor in my environment and I want to be able to interact with it within the blueprint system using player controller pawns. Currently, I can’t find a way to reference it. The question I asked was about accessing it as a player if it’s spawned from the level. I wanted to reference it but could not figure out a way how. I tried making it a variable by setting the spawned object as the object in the variable but I could not access that variable in my player blueprint. Currently, I’m spawning it from the player but since there’s multiple players, each player has their own object that they can modify so there could be multiple instances of the same object in the level during runtime. I hope this problem was explained effectively enough for someone to be able to help me.
