Down arrow in main menu only

I finally got the code that shows the result I want. It is the following (macros.html.twig file):

{% macro nav_loop(page) %}
  {% import _self as macros %}
  {% for p in page.children.visible %}
    <li> 
      <a {% if p.routable != false %}href="{{ p.url }}"{% else %}{% endif %}{% if p.children.visible.count > 0 and loop.length > loop.index %} class="submenu fa-angle-down"{% else %}{% endif %}>
        {{ p.menu }}
      </a>
      {% if p.children.visible.count > 0 %}
      <ul>
        {{ macros.nav_loop(p) }}
      </ul>
      {% endif %}
    </li>
  {% endfor %}
{% endmacro %}

I’ve included the loop.index condition to get the result I wanted.

Thanks for your help, anyway.
