Live view over wireless for iPad av Phase One

I have the XT camera with IQ4 150. I would like to use an iPad for live view, especially for focusing with tilt lenses, plus camera control.
According to release notes, version 2.3.4 of April, 2024 says Live View support for Phase One cameras is added.

Will this work over wifi directly from the camera body, or is cable required/recommended?
Are images saved to the internal card in the camera, or only transferred to the iPad?

Other recommendations?
