Complex Field’s ->set_min( $num ) working

Hi! How is ->set_min() on a complex field intended to work? Coming from ACF I thought it should “pre-build” as many rows as declared but it doesn’t seem to work as I’m setting it up. An example would be:

Container::make('post_meta', 'Configuration')
	->show_on_post_type('whatever_post_type')
	->add_fields(array(
    	Field::make('complex', 'whatever')
    		->setup_labels(array(
			'singular_name' => 'whatever rule',
			'plural_name' => 'whatever rules'
    		))
	    	->add_fields(array(
		    	Field::make('select', 'abc', 'ABC' )
		    		->add_options(array(
			    		'a' => 'A',
					'b' => 'B',
					'c' => 'C',
				)),
	    	))
		->set_min(1)
	));

Thanks for your support! Great developer framework!
