BlueprintNativeEvent in C++ Actor Component

Hello,

I am building an actor component that carries a few functions.

For development reasons I would like to make one of the functions a BlueprintNativeEvent and override it with a blueprint.

Where do I edit this inside the editor?
I cannot seem to create a child blueprint of the C++ class in the content browser.

The only place I can see the actor component is in the character blueprint…where I can attach it to the character correctly, but still cannot edit the functions.

Why would I not be able to create a BP child of the C++ class?

Is your class Bleuprintable? UCLASS(Blueprintable)

It was not, thanks!
