I am working on a messaging app, while creating the RootNavigator Function i keep getting a Type annotation error and failing to compile Ive tried to debug and getting no luck :(

import { createStackNavigator } from '@react-navigation/stack';import * as React from 'react';import { ColorSchemeName } from 'react-native';import NotFoundScreen from '../screens/NotFoundScreen';import { RootStackParamList } from '../types';import LinkingConfiguration from './LinkingConfiguration';import ChatRoomScreen from '../screens/ChatRoomScreen';export default function Navigation({ colorScheme, }: { colorScheme: ColorSchemeName;}) {  return (<NavigationContainer      linking={LinkingConfiguration}      theme={colorScheme === 'dark' ? DarkTheme : DefaultTheme}><RootNavigator /></NavigationContainer>  );}const Stack = createStackNavigator<RootStackParamList>();function RootNavigator() {  return (<Stack.Navigator screenOptions={( headerShown : false)} ><Stack.Screen name="ChatRoom" component={ChatRoomScreen} options={{ headerShown: true}} /><Stack.Screen name="Root" component={BottomTabNavigator} /><Stack.Screen name="NotFound" component={NotFoundScreen} options={{ title: 'Oops!' }} /></Stack.Navigator>  );}```
