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

It is an actor in the persistent level. I tried referencing it in with the character but it didn’t work and I couldn’t reference it in anything other than the level script but I also can’t reference the level script with the player so I resorted to spawning but that causes an issue of there being multiple objects. Is there any other way to reference an actor/static mesh with a player blueprint without looking at it or spawning it.
