It does not make cart empty when you enter the quantity ZERO

Actually I fixed this by modifying the code . here is the piece of code that I modified . would love if you can update the code and send an update in next version

function cqoc_add_js(){
     
    if (  is_checkout() ) {
        $plugin_version = $this->plugin_version;
        wp_enqueue_style( 'cqoc_checkout', plugins_url( '/assets/css/change-quantity-on-checkout.css', __FILE__ ), '', $plugin_version, false );
        ?>  
        <script type="text/javascript">
            <?php  $admin_url = get_admin_url(); ?>
            jQuery("form.checkout").on("keypress", "input.qty", function( event ){
                return event.charCode >= 48 && event.charCode <= 57;
            });
            
            jQuery("form.checkout").on("change", "input.qty", function( event ){
                var quantityValue = jQuery(this).val();
                if (quantityValue === '0') {
                    jQuery(this).val('');
                }
                
                $form = jQuery( 'form.checkout' );
                if ( $form[0].checkValidity() ){
                    var data = {
                        action: 'cqoc_update_order_review',
                        security: wc_checkout_params.update_order_review_nonce,
                        post_data: jQuery( 'form.checkout' ).serialize()
                    };
                    
                    jQuery.post( '<?php echo $admin_url; ?>' + 'admin-ajax.php', data, function( response )
                    {
                        jQuery( 'body' ).trigger( 'update_checkout' );   
                    });
                }
            });
        </script>
        <?php  
    }
}

I added a check inside the change event listener for quantity inputs (jQuery("form.checkout").on("change", "input.qty", function( event ){) to detect if the quantity entered is ‘0’. If it is, the script sets the input field value to an empty string, effectively treating it as empty.
