Chrome Extension notifications not showing contextMessage?

In my code, the contextMessage is not showing up I know it works fine with chrome.notifications.create, but if I use that then I can't make it so the notification never disappears without being closed or clicked on

function Notify(Title, Body, miniMsg, Url, Icon) {
    var notification = new Notification(Title, {
        icon: Icon||"Logo.png",
        body: Body,
        contextMessage:miniMsg
    });
    notification.onclick = function () {
        window.open(Url);
    }
}

Thanks!

The answer is simple: Compatibility.

You are trying to use a feature that isn't supported in Chrome without the webkit prefix, according to MDN. For a Google Chrome extension, it is suggested to use the chrome.notifications API.

Using the chrome.notifications API, you are unable to specify how long the notifications stay open. However, another option is to use the chrome.experimental.notifications API, which would prevent you from publishing your extension to the webstore, and has very little documentation.

You could also change the priority option in chrome.notifications.create to any integer between -2 to 2, where 2 is the highest, and would grant your notification the most display time.

Since you seem to be using the Notifications object, you might notice that your syntax does not match that shown in the MDN documentation. Primarily, there does not seem to be any contextMessage parameter for Notifications. As a side note, the onclick callback won't work, since the Url parameter is no longer executed in the current scope. The anonymous function will not be able to see the Url parameter passed into Notify. You also might want to check out compatibility and notes for Notifications.
