How do I add a custom WooCommerce quantity button?

add_action( 'woocommerce_after_add_to_cart_quantity', 'ts_quantity_plus_sign' );
 
function ts_quantity_plus_sign() {
   echo '<button type="button" class="plus" >+</button>';
}
 
add_action( 'woocommerce_before_add_to_cart_quantity', 'ts_quantity_minus_sign' );
function ts_quantity_minus_sign() {
   echo '<button type="button" class="minus" >-</button>';
}
 
add_action( 'wp_footer', 'ts_quantity_plus_minus' );
function ts_quantity_plus_minus() {
   if ( ! is_product() ) return;
   ?>
   <script type="text/javascript">
          
      jQuery(document).ready(function($){   
          
            $('form.cart').on( 'click', 'button.plus, button.minus', function() {
 
            var qty = $( this ).closest( 'form.cart' ).find( '.qty' );
            var val   = parseFloat(qty.val());
            var max = parseFloat(qty.attr( 'max' ));
            var min = parseFloat(qty.attr( 'min' ));
            var step = parseFloat(qty.attr( 'step' ));
 
            if ( $( this ).is( '.plus' ) ) {
               if ( max && ( max <= val ) ) {
                  qty.val( max );
               } 
            else {
               qty.val( val + step );
                 }
            } 
            else {
               if ( min && ( min >= val ) ) {
                  qty.val( min );
               } 
               else if ( val > 1 ) {
                  qty.val( val - step );
               }
            }
         });
      });
