Audio Setup with DDJ-SX3 and DJay Pro on Ipad

Not sure what I’m missing.

I was under the impression that when connecting my DDJ-SX3 to the iPad via the Lightning to USB3 Camera adapter cable that the audio from Djay Pro and the iPad would be routed through the Dj mixer/controller and I could work that way like with my standard Macbook Pro

Apparently, that is not the case. The controller gets recognized and works beautifully so far but the audio is still coming out of the iPad.

What am I missing?

Do I need any more/different cables/adapters?
