How to use the react-native-notifications.getInitialNotification function in react-native-notifications

async configure(params) {
		this.onRegister = params.onRegister;
		this.onNotification = params.onNotification;

		const initial = await NotificationsIOS.getInitialNotification();
		// NotificationsIOS.consumeBackgroundQueue();
		return Promise.resolve(initial);
	}
}

configure(options) {
        this.reduxStore = options.reduxStore;
        this.onRegister = options.onRegister;
        this.onNotification = options.onNotification;
        this.onReply = options.onReply;

        this.requestNotificationReplyPermissions();

        if (options.popInitialNotification) {
            NotificationsIOS.getInitialNotification().
                then((notification) => {
                    if (notification) {
                        const data = notification.getData();
                        if (data) {
                            ephemeralStore.appStartedFromPushNotification = true;
                            this.handleNotification(data, false, true);
                        }
                    }
                }).
                catch((err) => {
                    console.log('iOS getInitialNotifiation() failed', err); //eslint-disable-line no-console
                });
        }
    }
