How to replace ⚠️ NavigationBarItems (deprecated)

• ToolbarItemPlacement가 사용되는 곳

.navigationTitle("Daily Scrums")
//        .navigationBarItems(trailing: Button(action: {}) {
//            Image(systemName: "plus")
//        })
.toolbar {
    ToolbarItem(placement: .navigationBarTrailing) {
        Button(action: {}) {
            Image(systemName: "plus")
        }
    }
}
