How to Access/Use the Widget Carousel

I’ve found some articles for Widget Carousels, namely; this one here:
https://docs.unrealengine.com/latest/INT/API/Developer/WidgetCarousel/SWidgetCarouselWithNavigation/index.html

I’d like to use this widget, but cannot find it within UMG anywhere on 4.11.
Are these Carousel widgets in a newer version? The article didn’t specify…
If not, does anyone know how to access/use these? UMG doesn’t have anything named of the sort, nor can I seem to create a c++ class based off of the parent class type.

I do have a workaround of my own design that accomplishes what I want, but I’d prefer to use native components from Epic if one exists.

PS:
I did add the “WidgetCarousel” module to my project’s build.cs file.
