如何在出现时以编程方式触发NavigationLink

import SwiftUI

struct ContentView: View {
    @State private var isActive: Bool = false
    
    var body: some View {
        NavigationView {
            VStack {
                Button(action: {
                    self.isActive = true
                }) {
                    Text("触发导航")
                }
                .padding()
                
                NavigationLink(destination: DetailView(), isActive: $isActive) {
                    EmptyView()
                }
            }
            .navigationBarTitle("主视图")
        }
    }
}

struct DetailView: View {
    var body: some View {
        Text("目标视图")
            .navigationBarTitle("目标视图")
    }
}

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