display Slide Type selection on Markdown cells

My slides/sub-slides generally start with a Markdown cell for headings and whatnot, but this extension seems to only be showing the Slide Type selection on Code cells. Example:

Thanks!

Currently I open my notebook in the web-based jupyter notebook editor before converting to slides, only to get an overview if all my markdown cells have the right slide type. So it would be a nice productivity and quality of life boost if it would be displayed directly in vs code. Thanks.

Edit: I noticed that it is displayed when editing the markdown cells, but this is still painful if you want an overview.
