Display product attribute archive links

Hi there, I’m using WP page bakery and I’d like to display an archive product attribute on the page (a page with the products’ brand name).

Here’s what I achieved so far, but is not working:

function wpc_vc_shortcode( $atts ) {
	global $post;
	$attribute_names = array( 'pa_brand'); // Add attribute names here and remember to add the pa_ prefix to the attribute name
		
	foreach ( $attribute_names as $attribute_name ) {
		$taxonomy = get_taxonomy( $attribute_name );
		
		if ( $taxonomy && ! is_wp_error( $taxonomy ) ) {
			$terms = wp_get_post_terms( $post->ID, $attribute_name );
			$terms_array = array();
		
	        if ( ! empty( $terms ) ) {
		        foreach ( $terms as $term ) {
			       $archive_link = get_term_link( $term->slug, $attribute_name );
			       $full_line = '<a href="' . $archive_link . '">'. $term->name . '</a>';
			       array_push( $terms_array, $full_line );
		        }
		        echo $taxonomy->labels->name . ' ' . implode( $terms_array, ', ' );
	        }
    	}
    }
}
add_shortcode( 'my_vc_php_output', 'wpc_vc_shortcode');

Basically is what is achieved by this plugin:
