Laravel retrieve mailable view name

I'm tring to retrieve data like view and markdown names (not rendering view) example: emails.user.welcome for each mailable class in the app/Mail directory.

Var dump UserWelcome mailable class:

Route::get('rendermail', function() {

     $email = ( new App\Mail\UserWelcome() );

     return dd($email);

});

Var dump output
