How to: connect Sony PlayStation Dual Shock 4 (tvOS 13)

[BlankStar]

1. From the Apple TV Home screen, go to Settings.
2. Click on Remotes and Devices.
3. Click on Bluetooth.
4. Let it search for Bluetooth devices.
5. Take your Dual Shock 4 and press the PS & Share button at the same time until the light starts flashing (3-4 sec)
6. Select the Dual Shock in the list of Bluetooth devices

All done!

*edit*
Tested the DS4 with Real Racing 3 and it works like a charm. The PS-button works like the home-button on the Siri remote. X is to select and O is to go back. Both d-pad and analog sticks work as expected.
