Cannot find notification when snap_notify has type: 'native'

[javaspeak]

I have this code:

  export const onCronjob: OnCronjobHandler = async ({ request }) => {
  console.log('onCronjob called');
  switch (request.method) {
    case 'checkTransactions':
      return snap.request(
        {
          method: 'snap_notify',
          params: {
            type: 'native',
            message: `Hello, world!`,
          },
        }
      );
    default:
      throw new Error('Method not found.');
  }
};

I can see in the background console: onCronjob called

However I cannot see the notification in my chrome browser running on macOS.

As I am calling the cronjob every minute I sometimes see rate limiting error message:

 "message": "\"showNativeNotification\" is currently rate-limited. Please try again **later.",**

This infers that it is hitting the macOS notification system. However I cannot see the notfiication. Any ideas?

Thank you for your time
