### Customized Icon

The icon can be customized to any react node.

```jsx live
() => {
  const btnOnClick = () => {
    Notification.open({
      title: 'Notification Title',
      description: 'This is the content of the notification. This is the content of the notification.',
      icon: <Icon name="broadcast" size={25} color="#1890ff" style={{marginRight: 15}}/>
    });
  };
  
  return (
    <Button btnType="primary" onClick={btnOnClick}>Notification with customised icon</Button>
  );
}
```

</demo>
