ios - React Native App continues to work in background in Simulator but not on Real Device

Question

I am using React Native Expo and here is a simple code:

import React from 'react';
import * as Notifications from 'expo-notifications';

function Testing(props) {
 
 const sendNotification = () => {
        setTimeout(() => {
            const content = { title: "Hello World!" };
            Notifications.scheduleNotificationAsync({ content, trigger: null });
        }, 5000);
    }

 return (<Button title="Send Notification" onPress={() => sendNotification()}/>);

}

export default Testing;

I have not included Requesting permission code but it works.

When testing this on an IOS Simulator, I successfully get the notification after clicking the button and getting out of the app. But when testing on Real Device, it works when I am in the App Switcher Screen but does not work when App is in background.

Is there any additional thing to make it work on Real Device?
