Render BibLaTeX Key and generate plain text bibliography

Question

I would like to render the BibLaTeX keys in my markdown file and add a bibliography at the end of the text. Currently I use in a powershell script pandoc -s $Markdown --bibliography "C:\...\ref.bib" --csl "C:\...\styles\apa.csl" --citeproc --metadata link-citations=flase --to=gfm --output "$MarkDown-out.md"

Unfortunately HTML markup is added, which certain platforms other than Github do not render. How to generate a plain-text list of references or bibliographies in simple markdown?

<div id="refs" class="references csl-bib-body hanging-indent" line-spacing="2">
<div id="ref-MySource" class="csl-entry">
My Source
</div>
</div>
