Merci. Ça a fonctionné.
Exemple de code pour Head :
<script type='text/x-handlebars' data-template-name='/connectors/topic-footer-main-buttons-before-create/team-support'>
<div id="support">
<a href="link" title="Support-Icon" class="icon">
<svg class="fa d-icon d-icon-heart svg-icon svg-node" aria-hidden="true"><use xlink:href="#heart"></use></svg>
</a>
<a href="link" title="Support-Link" class="link">texte</a>
</div>
</script>
