I'm facing an issue on step 4 where I encounter the following error on GitHub action :
Run emacs ./config.org --batch -L ./ox-hugo -L ox-hugo.el --eval="(org-hugo-export-wim-to-md t)" --kill
Debugger entered--Lisp error: (void-function org-hugo-export-wim-to-md)
(org-hugo-export-wim-to-md t)
eval((org-hugo-export-wim-to-md t) t)
command-line-1(("./config.org" "-L" "./ox-hugo" "-L" "ox-hugo.el" "--eval=(org-hugo-export-wim-to-md t)" "--kill"))
command-line()
normal-top-level()
Approaches tried till now :
Changing (org-hugo-export-wim-to-md t) to (org-hugo-export-wim-to-md :all-subtrees)
Adding the expression (org-hugo-export-wim-to-md :all-subtrees) in single quotes and double quotes.

I happened to be working on a similar problem today. I had searched for guidance on it and I stumbled across Batch export of org-mode files from the command line which led me to fniessen/orgmk and in orgmk.el in particular.
After experimenting in my *scratch* buffer and asking Emacs' various help facilities a few questions, I bludgeoned my way to a standalone file containing Emacs Lisp code that appears to work independently of my initialization files.
$ touch export.el
$ emacs -q --batch -l export.el

The execution environment where I developed this is Emacs 28.2 on FreeBSD 13.1.
I haven't tried it out with Github Actions yet, but that's my next step.
