Need to add a oauth service for Netlify CMS login.
https://www.netlifycms.org/docs/github-backend/ (if we want to use github for authentication)

example config:

backend:
  name: github
  # Replace this with the GitHub repo you want to make change
  repo: github-username/target-github-repo
  # This site_domain and base_url are placeholders, replace with the correct one.
  site_domain: https://some-cms-domain.com # CMS's domain
  base_url: https://some-oauth-domain.com # OAuth Server's domain

For localhost, the default oauth provider is hosted by Netlify. This does not work in production.

https://infoportal.no/admin/#/ does not work...

• setup a dedicated oauth server for github authentication in Netlify CMS
