React-Navigation版本5中的`tabBarComponent`选项在哪里？

import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';

// 自定义底部导航栏组件
const MyTabBar = ({ state, descriptors, navigation }) => {
  return (
    <View style={{ flexDirection: 'row', backgroundColor: '#fff' }}>
      {state.routes.map((route, index) => {
        const { options } = descriptors[route.key];
        const label =
          options.tabBarLabel !== undefined
            ? options.tabBarLabel
            : options.title !== undefined
            ? options.title
            : route.name;

        const isFocused = state.index === index;

        const onPress = () => {
          const event = navigation.emit({
            type: 'tabPress',
            target: route.key,
            canPreventDefault: true,
          });

          if (!isFocused && !event.defaultPrevented) {
            navigation.navigate(route.name);
          }
        };

        return (
          <TouchableOpacity
            key={route.key}
            onPress={onPress}
            style={{ flex: 1, alignItems: 'center', paddingVertical: 12 }}
          >
            <Text style={{ color: isFocused ? '#000' : '#888' }}>{label}</Text>
          </TouchableOpacity>
        );
      })}
    </View>
  );
};

// 创建底部导航器
const Tab = createBottomTabNavigator();

// 设置底部导航栏的选项
const tabBarOptions = {
  tabBarComponent: MyTabBar, // 自定义底部导航栏组件
  activeTintColor: '#000', // 选中标签的文字颜色
  inactiveTintColor: '#888', // 非选中标签的文字颜色
  style: { backgroundColor: '#fff' }, // 导航栏的样式
};

// 创建导航栏
const AppNavigator = () => {
  return (
    <NavigationContainer>
      <Tab.Navigator tabBarOptions={tabBarOptions}>
        {/* 导航栏的路由 */}
      </Tab.Navigator>
    </NavigationContainer>
  );
};

export default AppNavigator;
