To delete an app on Apple TV, you can follow these steps:
1. **Navigate to the Home Screen**: Use the remote control to navigate to the home screen of your Apple TV.
2. **Select the App to Delete**: Using the remote, move the focus to the app you want to delete. Highlight the app icon on the screen.
3. **Press and Hold the Touch Surface**: On the remote, press and hold the touch surface (the top part of the remote) until the app icon starts to jiggle and a small "x" appears in the corner of the app icon.
4. **Delete the App**: Once the "x" appears, click on the touch surface to delete the app. You may be prompted to confirm the deletion. If so, select "Delete" or "Confirm" to proceed.
5. **Return to Home Screen**: Press the "Menu" button on the remote to return to the home screen once you have finished deleting the app.
The app should now be removed from your Apple TV. Keep in mind that some built-in apps cannot be deleted, and the ability to delete apps may vary depending on the version of the tvOS software installed on your Apple TV.
