Push Expo notification not received

Expo Development Tools
1

I created a simple Expo push notification app, and trying to send push notification using expo push token. I’m following expo documentation.

  1. When app is open - notification received
  2. When app is in background - not receiving
  3. When app is killed/closed - not receiving

Any guide, help documentation or example will be appreciated.

import * as Notifications from 'expo-notifications'
import * as TaskManager from 'expo-task-manager'
import * as BackgroundFetch from 'expo-background-fetch'
import * as Location from 'expo-location'

const LOCATION_TASK_NAME = 'background-location-task';


const requestPermissions = async () => {
  const { status } = await Location.requestBackgroundPermissionsAsync()
  if (status === 'granted') {
    await Location.startLocationUpdatesAsync(LOCATION_TASK_NAME, {
      accuracy: Location.Accuracy.Balanced,
    });
  }
};


TaskManager.defineTask(LOCATION_TASK_NAME,({data,error})=>{
  if(error){
    alert('Something went wrong with background locations')
  }
  if(data){
    alert('Something went right with background locations')
    const{locations} = data
  }
})

  
useLayoutEffect(() => {

    registerForPushNotificationsAsync().then(token => setExpoPushToken(token));

    notificationListener.current = Notifications.addNotificationReceivedListener(notification => {
      setNotification(notification);
    });

    responseListener.current = Notifications.addNotificationResponseReceivedListener(response => {
      //console.log(response);
    });


    return () => {
      Notifications.removeNotificationSubscription(notificationListener.current);
      Notifications.removeNotificationSubscription(responseListener.current);

    };
  }, []);

function handlerNotification() {
 
      schedulePushNotification()
      return () => {
        Notifications.removeNotificationSubscription(notificationListener.current);
        Notifications.removeNotificationSubscription(responseListener.current);
  
      };
      
  }
