I am trying to print all products of a brand on a taxonomy page.

I find the wp_querry but i cant print the current brand name of the brand to show all products in this page.

What to put on terms array to print the current page brand name?

// get products
$args = array(
  'post_type'      => 'product',
  'posts_per_page' => -1,
  'tax_query'      => array(
      array(
          'taxonomy' => 'pwb-brand',
          'field'    => 'name',
          'terms'    => array ('NAME?????')
        )
    )
);
$loop = new WP_Query( $args );
if ( $loop->have_posts() ) {
    while ( $loop->have_posts() ) : $loop->the_post();
        wc_get_template_part( 'content', 'product' );
    endwhile;
} else {
    echo __( 'not found anyhting.' );
}
wp_reset_postdata();
