chrome扩展通知

Question

从json对象我得到三个值，如title，price和url。通过使用镀铬丰富的通知，我可以显示值here is the example of what i'm showing。但是当我在亚马逊i want to show price's of this product like this打开产品时，而不是chrome.notification。这是我用于chrome.notifications的代码

function notifyMe(title,price) {
  if (!Notification) {
    alert('Desktop notifications not available in your browser. Try Chromium.'); 
    return;
  }

    var notification = new Notification(title, {
        icon: "../images/fev.png",
      body: price,
    });

    notification.onclick = function () {
      window.open("https://www.google.com/");      
    };
}

我应该如何获得输出，就像我展示的那样（不像chrome.notification）
