如何仅在长按手势SwiftUI上打开菜单

struct ContentView: View {
    var body: some View {
        Text("长按我打开菜单")
            .contextMenu {
                Button(action: {
                    // 点击菜单项的操作
                }) {
                    Text("菜单项1")
                    Image(systemName: "square.and.arrow.up")
                }
                
                Button(action: {
                    // 点击菜单项的操作
                }) {
                    Text("菜单项2")
                    Image(systemName: "trash")
                }
            }
    }
}
