ASRock Fatal1ty Z370 Gaming-ITX/ac USB 3.1 Header?

[HeroXLazer]

On the ASRock website, it says that this motherboard has a USB 3.1 Header, but I can't find the header on the pictures. Does anyone know where it is?

The spec sheet says that it has a USB 3.1 Gen 1 header, which is just renamed regular USB 3.0.
This header is located under the 24 pin connector.
