Laravel 5.7 change verification mail sender

Currently, when a Laravel user verification mail is sent, the sender is hello@example.com with a name of Example. How can I modify these values without changing files in the vendor directory (e.g. php artisan vendor:publish, but what?). I´ve looked at this question, \Illuminate\Auth\Notifications\VerifyEmail.php and \Illuminate\Auth\MustVerifyEmail.php, but while a markdown template is declared (which I´ve published to my resources to tweak it a little), there´s no code which actually sends the mail with sender and sender name!?
