I am looking for a way to show a kind of orange Alert on the Chrome icon to notify that a notification has been received. I have seen other questions with the same content, but the solutions have not worked for me.

show orange Windows taskbar icon orange when a Chrome Packaged app gets a notification

I have tried with

var appWindow = chrome.app.window.current();
appWindow.drawAttention();

But it doesn't work, I'm not doing something wrong

Thanks and greetings
