Markdown to Typst escapes #

I want to add a page break by writing `#pagebreak()` in Markdown, but if I convert it to Typst or use Typst to convert the Markdown to PDF, then the # is escaped to \\# and Typst ignores it.

Is there a way of getting pandoc to transfer a # to Typst without escaping it so I can write Typst functions in Markdown?
