Change language when citing page ('s. 1' instead of 'p. 1')

Question

I'm trying to change the language of in-text-citations. I'm using pandoc to convert my files from markdown (using obsidian with 'pandoc-plugin') so my citations usually look like this [@citekey] (this may also mean my problems are pandoc- or obsidian-related, so please let me know). When I write in english, latex has no problem with citations of specific pages: [@citekey, p. 1] gives 'author, year, p. 1'. However, when I write in norwegian, it leaves out the norwegian version of 'p.': [@citekey, s. 1], which gives me, 'author, year, 1', instead of 'author, year, s. 1'.

bibfile:

@article{auth_2020,
  title = {title},
  author = {auth},
  data = {2020}
}

For example for the md file:

---
lang: nb
---
he said this [@auth_2020, s. 1]

and the pandoc command:

pandoc --from markdown --to pdf -o C:\Users\pandoctopdf --pdf-engine=xelatex C:\Users\pandocmd --metadata bibliography=C:\pathtobib --citeproc -csl C:\pathtocsl

gives "he said this (auth, 2020, 1)" and not "he said this (auth, 2020, s. 1)". When using

---
lang: nb
---
he said this [@auth_2020, p. 1]

I get "he said this (auth, 2020, p. 1)"

It does, however, when citing 2 authors change from 'author and author' to the norwegian version; 'author og author'

Thank you
