Import custom panoramas in ipadOS 13.5.1

I bought SkySafari 6 Pro and i'm very happy with it. It is awesome! Cannot find a way to instal custom panoramas with the new version of ipadOS. I cannot use itunes anymore, but i can find some skysafari folders under the "Files" app (SkyData, SkyImages). How can i import my panorama using ipadOS version 13.5.1?
