如何通过SwiftUI中的.onTapGesture在两个不同的接口(没有Button\TextField)中使用两个列表中的ScrollViewReader？

import SwiftUI

struct ContentView: View {
    @State private var selectedTab: Int = 0
    @State private var scrollToIndex: Int? = nil
    
    var body: some View {
        VStack {
            TabView(selection: $selectedTab) {
                List {
                    ScrollViewReader { scrollViewProxy in
                        ForEach(0..<10) { index in
                            Text("Item \(index)")
                                .padding()
                                .id(index)
                        }
                        .onAppear {
                            if let scrollToIndex = scrollToIndex {
                                scrollViewProxy.scrollTo(scrollToIndex, anchor: .top)
                                self.scrollToIndex = nil
                            }
                        }
                    }
                }
                .tabItem {
                    Text("List 1")
                }
                .tag(0)
                
                List {
                    ScrollViewReader { scrollViewProxy in
                        ForEach(10..<20) { index in
                            Text("Item \(index)")
                                .padding()
                                .id(index)
                        }
                        .onAppear {
                            if let scrollToIndex = scrollToIndex {
                                scrollViewProxy.scrollTo(scrollToIndex, anchor: .top)
                                self.scrollToIndex = nil
                            }
                        }
                    }
                }
                .tabItem {
                    Text("List 2")
                }
                .tag(1)
            }
            
            Spacer()
            
            HStack {
                Button("Scroll to Item 5") {
                    selectedTab = 0
                    scrollToIndex = 5
                }
                .padding()
                
                Button("Scroll to Item 15") {
                    selectedTab = 1
                    scrollToIndex = 15
                }
                .padding()
            }
        }
    }
}

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