swiftUI how to add swipeActions to a navigation link label?

In the Apple Landmarks swiftui tutorial, how/where do you attach swipeActions? Looking for a behavior that when you tap a row it takes you to the detail, but when you swipe the row it will show the swipeActions. Tried at the end of the LandMarkRow line and also tried inside the LandMarkRow view where the row is being built.

error in code will repost
