Use `mhchem` KaTeX extension

[tahmidazam]

Is there a way to use the mhchem extension listed in the KaTeX docs? I'm using zero-md in my Anki template:

<script type="module" src="https://cdn.jsdelivr.net/npm/zero-md@3?register"></script>
<zero-md>
  <script type="text/markdown">{{Front}}</script>
</zero-md>

Thanks!
