"section-index plugin couldn't detect a supported theme to adapt. It probably won't work as expected" when using filesize-reduction method.

I'm getting the "section-index plugin couldn't detect a supported theme to adapt. It probably won't work as expected." error when I trying using section-index (with material theme installed) in conjunction with the filesize-reduction partial (https://git.cwp.pnp-hcl.com/CWPdoc/dx-mkdocs/blob/main/theme_overrides/partials/nav-item.html). Is there anything I can do about that? I'd love to keep using section-index, but my total HTML file size is too big for GitHub Pages to render.

NVM, I was on an old version I think.
