NOTIFICAÇÃO NÃO APARECE NO CELULAR

Estou com um problema, meu site mostra notificações apenas se for acessado pelo computador. Quando acessado pelo celular, ele pede para ativar as notificações, porem ele não mostra.

Codigo da função:

(function(global, factory) {
 "use strict";
 if (typeof define === "function" && define.amd) {
 define(function() {
 return new(factory(global, global.document))
 })
 } else if (typeof module !== "undefined" && module.exports) {
 module.exports = new(factory(global, global.document))
 } else {
 global.Push = new(factory(global, global.document))
 }
})(typeof window !== "undefined" ? window : this, function(w, d) {
 var Push = function() {
 var self = this,
 isUndefined = function(obj) {
 return obj === undefined
 },
 isString = function(obj) {
 return String(obj) === obj
 },
 isFunction = function(obj) {
 return obj && {}.toString.call(obj) === "[object Function]"
 },

 } else if (w.external && w.external.msIsSiteMode) {
 w.external.msSiteModeClearIconOverlay()
