如何在SwiftUI中从ForEach动画特定的按钮？

import SwiftUI

struct ContentView: View {
    @State private var buttons = ["Button 1", "Button 2", "Button 3"]
    @State private var selectedButton: String?
    
    var body: some View {
        VStack {
            ForEach(buttons, id: \.self) { button in
                Button(action: {
                    withAnimation {
                        self.selectedButton = button
                    }
                }) {
                    Text(button)
                        .padding()
                        .foregroundColor(.white)
                        .background(self.selectedButton == button ? Color.blue : Color.gray)
                        .cornerRadius(10)
                }
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
