Anyone know what the variable type for the red pin is?

I’m talking about that input for the Bind to event dispatcher node. If i wanted to make my own node with that as an input, anyone know what the variable type is? or if I can’t make it a node, how I would do it in c++?

Isn’t the red pin for BOOL ?
I am fairly certain they keep the same color scheme across the board.

I am not even going to try and cover the fact i was wrong lol

I’m fairly certain that it’s not a bool.
Edit: I mean, i know bool is red, but the thing i’m looking for isn’t bool

I know how to work with event dispatchers in blueprints. What I’m asking about is how to make a function that takes an event dispatcher as an input like the Bind function does.
