How to use with next export?

[BasicPixel]

I am trying to use next-sitemap on a website with static HTML export, and I am having two problems:

1. I can't use getServerSitemap, because getServerSideProps is not supported with next export.
2. Even without server sitemap, the sitemap.xml file is not included in the export out directory, so it cannot be accessed in production.

I would appreciate if anyone has solutions to one of or both of the problems. Thanks in advance!

UPDATE: It now works as expected, except I need to next export AFTER next-sitemap for it to work in my github actions workflow.
My scripts section of package.json looks like this:

"scripts": {
  "dev": "next dev",
  "build": "next build",
  "start": "next start",
  "lint": "next lint",
  "postbuild": "next-sitemap && next export"
},
