In my UIKit apps, collection view cells that have a context menu gain an Ask Siri item in iOS 27 without me doing anything. In my SwiftUI app I have a LazyVGrid containing a ForEach of CellView which is a Button that has a contextMenu, yet there’s no Ask Siri button in the context menu. What determines whether or not it will be added? What do I need to do to allow the system to add it?
