Help with Automatic Closing door (SD92)

I want to open the back door myself
The backdoor close automatic

In driving view there is a Yellow button for pram (puppenwagen) when pressed Backdoor open and keep open until pressed again.

This button is it possible to program it for a shortcut so when pressing a keyboard key i can do the same
so far i havent found it in shortcut keyboard keys

Options => Keyboard => Add Vehicle Key Event => Buggy Switch and select the key that you want.

Thanks
