如何显示弹出视图？

struct ContentView: View {
    @State private var showingPopover = false
    var body: some View {
        Button("Show Menu") {
            showingPopover = true
        }
        .popover(isPresented: $showingPopover) {
            Text("Your content here")
                .font(.headline)
                .padding()
        }
    }
}
