Pandoc does not seem to include .rtf files. Can I add them

I am using Ubuntu 22.04 LTS

I wanted to convert .rtf files to PDFs using Python.

I found this on stackoverflow:

import pypandoc

def convert_rtf_to_pdf(input_rtf, output_pdf):
    pypandoc.convert_file(input_rtf, 'pdf', outputfile=output_pdf)

if __name__ == "__main__":
    input_rtf_path = "Path to your RTF File"
    output_pdf_path = "path to your pdf file output with name /output.pdf"

    convert_rtf_to_pdf(input_rtf_path, output_pdf_path)

But I get this error:

RuntimeError: Invalid input format! Got "rtf" but expected one of
these: commonmark, creole, csv, docbook, docx, dokuwiki, epub, fb2,
gfm, haddock, html, ipynb, jats, jira, json, latex, man, markdown,
markdown_github, markdown_mmd, markdown_phpextra, markdown_strict,
mediawiki, muse, native, odt, opml, org, rst, t2t, textile, tikiwiki,
twiki, vimwiki

Can I somehow add .rtf files to Ubuntu pandoc, then convert them to PDF?

Looking further, I found this, which shows rtf is available:

print(pypandoc.get_pandoc_formats())
