Getting Markdown formated content into Notion (and having it parsed!)

Has anyone been successful in getting formatted text into Notion successfully? Specifically, I’m trying to write to a database item content.

I’ve used the Markdown module to convert HTML to markdown. I’ve had a couple of occasions where the module has hiccuped and the last part isn’t converted, but generally, markdown is getting to Notion, but it’s not being “parsed” by Notion. Is there something that I should be doing in the Notion module to tell it that the text is preformatted? There’s nothing obvious that I’m finding - only clear options are to pass content as paragraph, heading, etc…
