How to remove "Create account" Signup from Amplify Auth UI with React Native?

I have a login screen in a react native app with Amplify Auth. below is the code with the default Authenticator configuration. I'm using Amplify V6 Does anyone know how to remove the Signup functionality? I need to remove "Create Account" my app doesn't need it. thanks

import { StatusBar } from 'expo-status-bar';
import { StyleSheet, Text, View, Button } from 'react-native';
import { Amplify } from 'aws-amplify';
import { USER_POOL_ID, USER_POOL_CLIENT_ID, IDENTITY_POOL_ID} from '@env'
import { getCurrentUser, signOut, signIn } from 'aws-amplify/auth';
import { withAuthenticator, useAuthenticator} from '@aws-amplify/ui-react-native';

const amplifyConfig = {
  Auth: {
    Cognito: {
      userPoolId: USER_POOL_ID,
      userPoolClientId: USER_POOL_CLIENT_ID,
      identityPoolId: IDENTITY_POOL_ID,
    }
  }
}
Amplify.configure(amplifyConfig);

async function handleSignOut() {
  try {
    await signOut();
  } catch (error) {
    console.log('error signing out: ', error);
  }
}

  function App() {
  return (
    <View style={styles.container}>
      <Text >Open up App.js to start working on your app!</Text>
      <StatusBar style="auto" />
      <Button title="Sign Out" onPress={handleSignOut} />
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#fff',
    alignItems: 'center',
    justifyContent: 'center',
  },
});


export default withAuthenticator(App);
