I assume you only need something "clickable", if so this should do trick:
// define notification object
var urlAction =
{
actionLabel: "https://www.google.it",
eventHandler: function () {
Xrm.Navigation.openUrl("https://www.google.it");
}}
var notification =
{
type: 2,
level: 4, //error
message: "show URL message",
showCloseButton: true,
action:urlAction
}
Xrm.App.addGlobalNotification(notification).then(
function success(result) {
console.log("Notification created with ID: " + result);
// perform other operations as required on notification display
},
function (error) {
console.log(error.message);
// handle error conditions
}
);
