How can I add a success flash message for the password reset functionality of Laravel?

I'm using Laravel 5.1 and the built-in auth functionality. When testing it, however, I noticed there is no "Success" message when a user fills out the forgotten password form, the page simply refreshes, although the form does work.

How can I set a success variable? I can't find the method that controls this anywhere.

Thanks
