You should use the following code in Head instead:

<script type="text/discourse-plugin" version="0.8">
    api.addCommunitySectionLink({
      name: "unread",
      route: "discovery.unread",
      title: I18n.t("some.unread.title"),
      text: I18n.t("some.unread.text"),
      icon: "fa-envelope"
    });
</script>

<script type="text/discourse-plugin" version="0.8"> is important if you want to use the API.

That should work better. :+1:
