Select a feed to be displayed in the Apple TV App Store. It gives potential users a content preview and entices them to click through.
The feed will be the Top Shelf Image on a user's Apple TV while they have your app selected in the App Store.
Here is what it would look like in the App Store:
Navigate to App Creator > Design, and select Apple TV Top Shelf on the left side toolbar.
Navigate to Choose Feed. Your feeds pop up.
Click Select next to the feed you would like to add and click Save!
