Is there a way to add a sitemap to Figma Sites?

Google doesn’t want to properly index my Figma Sites site and I was wondering - is there a way to add a sitemap in plain text/html as there is no CMS yet?

It’s been two weeks since I’ve published our company’s new website and it’s still indexing the old site that was hosted on the same URL. I’ve sent requests to Google but it’s still not working properly.
