UUserWidget::NativeOnDrop

Good day, guys.

I am trying to make an inventory feature of my game. In the code below, I am trying to implement the NativeOnDrop of the UUserWidget, but I can not implement it. The UE_LOG is not printing.

Thank you guys in advance!

Do you have NativeOnDragDetected somewhere that creates a DragDropOperation? How are you testing it?
