Where do I download the ARK Development Kit?

I see a lot of people talking about this and saying it is downloaded in the Epic Games Launcher / Store Page but I do not see anything called ARK Development Kit in the store. My goal is to make a map for ARK if that helps direct me to the correct place.

----EDIT —

Figured out it is not called the Ark Development Kit in the Epic Games Launcher but called Ark Editor. Not intuitive, will keep moving forward.
