Smart Controller and Split Control

[Quikdraw13]

I have a Mavic 2 Pro with the smart controller. I would like to use an IPad Pro to allow my partner to run the camera controls, especially for taking photos, since she has a more artistic eye, loves to set everything manually, and will be editing the raw files. I want to let her to do what she enjoys and is good at, while I get to have my fun.
Is this possible with the smart controller? What apps and cable will I need?

Hello
You need another remote controller connected to the ipad and setup as a secondary controller
