Formatting author names with orcid and affiliations in RMarkdown

Question

I am unable to make the title page using RMarkdown the way I usually do using LaTeX.

Here is my current code in markdown:

---
title: 'Research on the use of mirrors on rooftops to focus on Starlink satellites to burn them down because they interfere with amateur astronomy'
author:
- Heinz Doof, University of Okomba, Lucario 52500, Wakanda.
- Phenias Krill, Barry University, Millet Department, Dublin DD 0562, Ireland.
- Ferb Mayo, University of Okomba, Lucario 52500, Wakanda.
- Pablo Macro, Barry University, Millet Department, Dublin DD 0562, Ireland.
date: "19 June 2023"
output:
  pdf_document:
    number_sections: yes
  word_document: default
  html_document:
    df_print: paged
---

And this is the corresponding output:

I want to add the ORCiD links and group the affiliations using numberings. Something like this:

For pdf output, to format author names with orcid link and affiliations, you may try the authblk and orcidlink latex package.

Now to include the affiliations for each author, I have used the yaml keys name, affil-id, id, affiliations. These will act as interpolated variables as pandoc template. So copy the contents of pandoc template for latex into a file default.tex and then replace the line in the default.tex file \author{$for(author)$$author$$sep$ \and $endfor$} with the following,

\usepackage{authblk}
\usepackage{orcidlink}
\renewcommand\Affilfont{\small}

$for(author)$
\author$if(it.affil-id)$[$it.affil-id$]$endif${$it.name$}
$endfor$

$if(affiliations)$
$for(affiliations)$
\affil[$it.id$]{$it.name$}
$endfor$
$endif$

and then use this template in the rmarkdown file using template yaml key.
