How do I change a Function's Input Parameter Variable pin type to Delegate?

[soulzero]

While looking at the Blueprints for Pro Main Menu I noticed that some of the Input Parameter variable pin types for some of the Functions are set to Delegate. How do I change a Function’s Input Parameter Variable pin type to Delegate? I have gone through the entire list and can’t seem to find a Pin type for Delegate. Please see the Picture below. Thanks.

Delegates as Parameter

You can add delegate parameter to function by dragging event pin from event dispatcher and dropping it on the function. [258154-delegateparameter.png] [258155-delegate.png]
