Table Of Contents (TOC) in Org mode

Gitlab has support for Org mode format.

When exporting that file to HTML, the result is the following:

Whereas, if that same org-mode file is rendered in Gitlab, the result is:

Which does not show the Table of Contents…

Is it possible that Gitlab can render the Table of Contents?
Maybe @axil or @toon can bring some light on this…
Best Regards.
