Apple Watch - Full Screen - Beginner Question

It is not possible for external developers to hide the time in watch apps.

Following the these instructions will not work for me:

Enabling Full Screen Mode
By default, when a watchOS app is running, the system reserves a strip of space across the top of the screen to display the time. The app’s content is only displayed in the area below the time.
In watchOS 4 and later, SpriteKit and SceneKit scenes can fill the full screen. When full screen mode is enabled, the SpriteKit or SceneKit scene extends up, under the time. The system still displays the time in the upper-right corner with a gradient behind it, making it clearly visible against the scene. 
To enable full screen mode, place a SpriteKit or SceneKit scene as the interface controller’s only content. Then, in the interface controller’s Attribute inspector, enable the Full Screen attribute.

What is not working for you?

I follow the instructions listed, and the small digital time still appears in the upper right corner.
