Ayuda al mostrar un enlace en la tabla de pedidos de Woocommerce

Ayuda al mostrar un enlace en la tabla de pedidos de Woocommerce | EDteam
Estoy desarrollando un módulo para woocommerce que consume una API, en la parte posterior muestra el enlace correctamente de cada pedido que se realiza, pero mi problema es cuando quiero insertar este enlace en la parte que el cliente ve, en Pedidos, a continuación desde el enlace Consulte Deseo que aparezca una factura y cuando haga clic en descargar el PDF proporcionado por la API.
Con este código inserto el botón "Factura"
add_filter( &#39;woocommerce_my_account_my_orders_actions&#39;, &#39;add_my_account_my_orders_custom_action&#39;, 10, 2 );
function add_my_account_my_orders_custom_action( $actions, $order ) {
   if ( $order-&gt;has_status( &#39;completed&#39; ) ) {
       $action_slug = &#39;descargar_factura&#39;;
       $actions[$action_slug] = array(
           &#39;url&#39;  =&gt; $data-&gt;links-&gt;pdf,
       &#39;name&#39; =&gt; &#39;Factura&#39;,
       &#39;class&#39; =&gt; &#39;factura&#39;,
       );
   }
   return $actions;
} ```

Me muestra el texto FACTURA, pero no adjunta la URL para la descarga de la factura.

Adjunto el código completo donde realiza la llamada a la API y obtiene las URL.
