How to export publication to subdirectory

[fkgruber]

Hi In the academic theme you can put publications on a directory so you can add other stuff like bibtex etc. See for example https://github.com/wowchemy/starter-hugo-academic/tree/main/content/publication

However, in ox-hugo I tried :EXPORT_FILE_NAME: my_paper/index.md

but when I export it is located in publication/index.md. It ignores the subdirectory. How can I export the subtree to a subdirectory

I found in the documentation that we can use the :EXPORT_HUGO_SECTION_FRAG property to set the subdirectory.
