Comfort opening tailgate

Good evening, I have recently been the owner of a used Karoq Selection Bj 12/2023, 110kW Diesel with Kessy. The tailgate can be opened and closed electrically from the driver’s seat at the push of a button and the tailgate. Unfortunately, the contactless opening or the virtual pedal of the tailgate is missing. Since both of us, my wife and I are a little older grandparents, the above equipment would be helpful for larger purchases. Can you retrofit this? What do I need to do with it? Tergert
