How to generate intermediate LaTeX when converting qmd to pdf?

[dpo]

Description

I have the preamble

---
title: "My Title"
author:
  - name: Me
format:
  pdf:
    documentclass: scrartcl
---

When converting my qmd document to PDF, I would like to inspect the intermediate LaTeX (including the template). The only command I found to convert from qmd to tex uses the pandoc executable bundled with Quarto:

quarto pandoc -o mydoc.tex --standalone mydoc.qmd

However, Pandoc says

[WARNING] Could not deduce format from file extension .qmd
  Defaulting to markdown

and the preamble of the LaTeX file uses the article document class, not scrartcl.

What's the correct incantation?

Add keep-tex: true in your frontmatter (https://quarto.org/docs/output-formats/pdf-basics.html#latex-output).

Thank you! I missed it in there.
