According to the docs tvOS 18+ supports the new NavigationTransition and the matchedTransitionSource and navigationTransition(.zoom(sourceID: id, in: namespace)) modifiers, however they don't seems to work.
Taking the DestinationVideo project example from the latest WWDC the matchedTransitionSourceis marked with #if os(iOS)
Is it supported by tvOS or is it for iOS only?
