Export to pdf using workflow

Hi, after one year of inactivity I’m writing a new book with scrivener.
I use many citations, a few mathematical formula and I downloaded the example of workflow written in scrivener.
I confess that my understanding of pandoc templates and many aspects behind the scripts are not easy for me but, using this workflow I can put bibliography (I use a zotero applescript and bib file) and also formula (block or inline). Perhaps one day I can fully understand what there is inside the script!
I’d like export also in pdf but in the workflow I have only docx, latex and odt files.
What steps I have to do to obtain a pdf file inside this workflow?
Any advice for learning (beginning user) something about pandoc, pandocomatic etc?
Thank you.
