* In rare situations, a push token may be changed by the push notification service while the app is running.
* When a token is rolled, the old one becomes invalid and sending notifications to it will fail.
* A push token listener will let you handle this situation gracefully by registering the new token with your backend right away.
* @param listener A function accepting a push token as an argument, it will be called whenever the push token changes.
* @return A [`Subscription`](#subscription) object represents the subscription of the provided listener.
* @header fetch
* @example Registering a push token listener using a React hook.
* ```jsx
* import React from 'react';

* import { registerDevicePushTokenAsync } from '../api';
*
* export default function App() {
* React.useEffect(() => {
* const subscription = Notifications.addPushTokenListener(registerDevicePushTokenAsync);
