How to display products by attribute?

Question

WordPress

hello. tell me how to display goods by Attribute ???

added a new attribute label pa_metka to product attributes with the values ​​New, popular and recommended.
conclusion.

<?php 
            $args = array(
              'post_type' => 'product',
              'post_status' => 'publish',
              'ignore_sticky_posts'   => 1, 
              'product_cat' => $term->slug
            );

            $products = new WP_Query( $args );


          if ( $products->have_posts() ) :
          ?>
          
            <?php while ( $products->have_posts() ) : $products->the_post(); ?>
            <!-- item -->

            <?php  
            global $product;
            echo $product->get_attribute('new');
?>
   <pre><?php print_r($product); ?></pre>         
            
            

              <?php wc_get_template_part( 'content', 'product' ); ?>
            <!-- // item -->
            <?php endwhile; // end of the loop. ?>

    			<?php endif; ?>

And the problems begin,
1. not all products appear, only 12 appear randomly,
2. I try to pull out the value of the tag so that I can then sort new items to new items, popular to popular.

PS: as a standard, I did it through record labels,

but the client wants it through an attribute

<?php 
         $args = array(
          'post_type' => 'product',
          'post_status' => 'publish',
          'ignore_sticky_posts'   => 1, 
          'product_cat' => $term->slug
        );

         $products = new WP_Query( $args );
         if ( $products->have_posts() ) :
          ?>

          <?php while ( $products->have_posts() ) : $products->the_post(); ?>
            <!-- item -->

            <?php  
            $attributes = $product->get_attributes();
            foreach ( $attributes as $attribute ):
    $attribute_data = $attribute->get_data(); // Get the data in an array

    $attribute_name = $attribute_data['name']; // The taxonomy slug name
    $attribute_terms = $attribute_data['options'][0]; // The terms Ids
    // echo '<pre>'; print_r($attribute_terms); echo '</pre>'; 

    if ($attribute_name == 'метка' & $attribute_terms == 'Новинки' ) {
     wc_get_template_part( 'content', 'product' ); 
    }
 endforeach;
 ?>
