function for filtering Woo Commerce shipping methods

Trying to add a function to my child theme’s function.php file that will make the shopping cart page show just 1 shipping option if the cart only has items from a particular shipping class. Getting close but still down’t seem to quite have it working right. Any thoughts? Thanks.

/*just show flat rate shipping method when only paper patterns are in the cart*/
function only_show_flat_rate_shipping_with_patterns( $rates )	{

	$targeted_class = 901; // <== the pattern ship shipping class
	
    // Loop through cart items to find out if any hasn't the targetted shipping class
    foreach( WC()->cart->cart_contents as $key => $values ) {
        // IF One item is found without this shipping class
        if( $values[ 'data' ]->get_shipping_class_id() != $targeted_class ) {
            return $rates; // <== FOUND! We exit returning all Shipping rates
        } 
    }
	
	//if no exceptions to the shipping class, hide all methods but flat rate
	unset( $rates['usps:D_PRIORITY_MAIL']);
	unset( $rates['ups:4:01']);
	unset( $rates['ups:4:02']);
	unset( $rates['ups:4:03']);
	
	return $rates;
	
}

add_filter( 'woocommerce_package_rates',     'only_show_flat_rate_shipping_with_patterns', 10, 2 );
