Spawning a creature when the player has a gun

Hello,

I’ve been working on getting to grips with UEFN and I’d like some help with a certain in-game scenario. In a nutshell, I’d like to spawn creatures when the user runs over various triggers (I can do that part) but ONLY if the user has a shotfun in their inventory. I’ve looked at the likes of the conditional button and the standard trigger but none seem to satisfy this requirement.

Has anyone had experience working with this kind of function before?
