How to use Djay Pro AI (iOS) with AUM on iPad Pro?

Hi, I have just discovered AUM AUM - Audio Mixer | and am keen on exploring how to use Djay Pro AI together with AUM on my iPad Pro 2020. Anyone with experience/ideas?
Is it so that Djay Pro AI needs to be Audio Unit (AU) and/or Inter App compatible before integration between AUM and Djay Pro AI is possible? Cheers

AUM and AudioBus were working in DJay 2 I don’t know why they remove this fantastic option in Djay Pro ??? I was very disappointed too
