Controlling a 3 Pro with RC-N1?

[Filmarik]

When the first Mavic 3 was released, it came with the RC-N1.
That suited me fine as it allowed me to keep using my favourite 8 inch tablet as a flying screen.
When the Mavic 3 pro was released, it came with an integrated screen controller.
I sold that without even trying it because its phone-sized screen was too small.
I do a lot of serious photography and rely on having a screen large enough to see what's going on.

What's that thing sticking from behind the tablet?
