问题
According to this page, we can send a notification on demand without going through a model. How do I do the same using slack?
I want to do something like this:
$emailAddress = 'my email address';
Notification::route('mail', $emailAddress)
            ->route('slack', 'what do I put here?')
            ->notify(new TestNotification());
The code works without the slack line.
Edit: this StackOverflow question uses the on demand method

You should you put the Slack Webhook URL. See: https://laravel.com/docs/5.5/notifications#routing-slack-notifications
 Notification::route('slack', 'https://hooks.slack.com/services/ZZZZ/YYYY/XXX')->notify(new DailyStats());
