iPhone adapter for Behringer X32

New

I am beginner and have I guess a simple question. Is there an adapter I can use to have sound stream through my IPhone from the soundboard? For example I use a video camera that plugs directly into the X32 and I have sound from the board opposed to the camera. I stream through Stream yard and would love to do this using my IPHONE 12 pro Max using sound from the soundboard. Thank you
