requestSceneSessionActivation for Window With Prominent Presentation Style

I have code to create a new window with UIApplication.shared.requestSceneSessionActivation. I now want that window to have the prominent presentation style (UIWindowScenePresentationStyleProminent) on iPadOS 15. But it is not clear to me how to get that presentation style when using requestSceneSessionActivation. What am I missing?
