trouble using setOption for responsive option

Hi I am probly just doing something silly but can’t get setOption to work

in my final js file en queued I have

$( '.slick-slider-wrapper .slick-slider' ).slick( 'setOption', 'responsive', [
		{
			breakpoint: 480,
			settings: {
				slidesToShow: 1,
			}
		},
		{
			breakpoint: 768,
			settings: {
				slidesToShow: 2,
			}
		},
		{
			breakpoint: 992,
			settings: {
				slidesToShow: 4,
			}
		},
	],
	true
	)

This is inside a document.ready. Then the added dep like so

wp_register_script('b4st-js', get_template_directory_uri() . '/theme/js/b4st.js', array('slick-slider-core'), false, null, true);
		wp_enqueue_script('b4st-js');

Has something changed or do you see a mistake in what I am doing?

Thank you for the plugin.
Best Regards
