Unable to define and use heleper function value as global variable in node js

I am trying to showing notification in my project so thats why i am creating helperFunction and call in main server.js file and define as global variable but when it return value [object promise],If i call helper function in my other controller it return value but as global variable it return object promise

************ helper function *************

const fs = require('fs');
const Sequelize = require('sequelize');
const Op = Sequelize.Op;
const models = require(appRoot + '/models');

const helpersService = () => {
 const getNotification = async () => {
        
        var findStatus = 0;

        if (findStatus != '' && findStatus != null) {
            var whereOptions = {
                is_read: {
                    [Op.iLike]: '%' + findStatus + '%'
                }
            }
        } else {
            var whereOptions = {}
        }

        let getNotifications = await models.Notifications.findAll({
            include: [{
                attributes: ['id', 'full_name', 'email'],
                model: models.Users,
                as: 'user'
            }],
            where: whereOptions,
            raw: true,
        });

        
        return getNotifications;


    };

    return {
        getTranslatedText,
        notificationStatus,
        getNotification,
    };
};

module.exports = helpersService;
