如何在不使用旧UISegmentControl的情况下改变swiftUI中分段控制的半径

struct CustomSegmentedPickerStyle: PickerStyle {
    func makeBody(configuration: Configuration) -> some View {
        Picker("", selection: configuration.selection) {
            ForEach(0..<configuration.options.count) { index in
                Text(configuration.options[index])
                    .tag(index)
            }
        }
        .pickerStyle(SegmentedPickerStyle())
    }
}

struct ContentView: View {
    @State private var selectedOption = 0
    
    var body: some View {
        VStack {
            Picker("", selection: $selectedOption) {
                Text("Option 1")
                Text("Option 2")
                Text("Option 3")
            }
            .pickerStyle(CustomSegmentedPickerStyle())
            
            Text("Selected Option: \(selectedOption + 1)")
        }
    }
}
