Strapi for Push Notification?

EDIT : New code

'use strict';
/**
 *  news controller
 */
const { createCoreController } = require('@strapi/strapi').factories;
module.exports = createCoreController('api::news.news', ({ strapi }) => ({
    async create() {
        await strapi.service('api::news.news').createNew({
            ...ctx.request.body.data,
        });
        strapi.log.debug('A new News was added');
        try {
            await strapi.services.notifications.sendMessageToDevices(tokens, title, description, data);
        } catch(err) {
            strapi.log.error('Notifications/sendMessageToDevices', err);
        }
    }
}));
