Using Quarto in Blogdown

Question

I would like to use the quarto markdown format for rendering blog posts in R's blogdown package, however am struggling to get blogdown/hugo to notice the output index.md or index.html files that constitute blog posts.

I found this post which mentions the post itself is a quarto doc used in blogdown, but I'm unable to recreate the steps.

So far I render the quarto document which outputs index.html in the post directory but after blogdown::build_site and launching the server, no dice. Not even a mal-formed post being rendered.
