How can I enable self-parking feature on my Audi A6?

I recently purchased an Audi A6 and heard about its amazing self-parking feature. Can anyone guide me on how to activate it and use it effectively?

To enable self-parking feature, press and hold the button on the console labeled 'P'. The car will then search for a parking spot and once found, it will prompt you to stop and engage reverse gear. Follow the instructions on the screen and the car will automatically park itself.
