Laravel Queue mailable via tinker

gistfile1.txt

// Create mailable, e.g. MailableTest
php artisan make:mail MailableTest --markdown=emails.mailable-test

// Run horizon or queue worker

// Open tinker
$mailable = (new \App\Mail\MailableTest())->onQueue('queue-name');
Mail::to('somemail@example.com')->send($mailable);

This does not seem to work. Laravel will send the email synchronously.
Below worked:

Mail::to('no-reply@carlite.com.sg')->queue($mailable);

@carltondickson Thanks, @dilab method works!
