Question about Samsung SKK-DD connector

I have a Washing machine with the model name " WW80M642OBW/EG " and the serial number " 0TSL5ADN600015Z ". And a Dryer with the model name " DV8TTA220AE/EG " and the serial number " 0VMG5ABNA00441D ". I had bought the Samsung SKK-DD intermediate installation frame for this. When I called the technician yesterday, I was told that this intermediate mounting frame is not suitable for my machines (unfortunately, this was not apparent at the time of my purchase) and that I need the SKK-DF intermediate mounting kit for my machines. When I search for SKK-DF on the internet, I find that it only contains two brackets and not an intermediate mounting frame. Now my question: Is there really no intermediate mounting frame for my machines that I can install without any problems? Or do I use these brackets to be able to attach the SKK-DD intermediate mounting frame correctly? To be honest, I can't get my head around the idea of simply placing both machines on top of each other and only connecting them with two brackets; it looks anything but neat.
