我想用React Native中的另一个屏幕替换部分屏幕

import React from 'react';
import { View, Button } from 'react-native';
import { createStackNavigator } from '@react-navigation/stack';

// 创建导航器
const Stack = createStackNavigator();

// 屏幕组件1
const Screen1 = ({ navigation }) => {
  return (
    <View>
      <Button
        title="替换为屏幕2"
        onPress={() => navigation.replace('Screen2')}
      />
    </View>
  );
};

// 屏幕组件2
const Screen2 = ({ navigation }) => {
  return (
    <View>
      <Button
        title="替换为屏幕3"
        onPress={() => navigation.replace('Screen3')}
      />
    </View>
  );
};

// 屏幕组件3
const Screen3 = () => {
  return (
    <View>
      <Button title="返回首页" onPress={() => navigation.popToTop()} />
    </View>
  );
};

// 导航器组件
const Navigator = () => {
  return (
    <Stack.Navigator initialRouteName="Screen1">
      <Stack.Screen name="Screen1" component={Screen1} />
      <Stack.Screen name="Screen2" component={Screen2} />
      <Stack.Screen name="Screen3" component={Screen3} />
    </Stack.Navigator>
  );
};

export default Navigator;
