From GitHub Support when clarifying misleading documentation of https://docs.github.com/en/rest/activity/notifications?apiVersion=2022-11-28#list-notifications-for-the-authenticated-user%5D

Thank you for reaching out to GitHub Support!

That section of the documentation is incorrect -- thank you for bringing this to our attention. At the moment, all notification API endpoints only support authentication using personal access token classic: https://docs.github.com/en/rest/activity/notifications?apiVersion=2022-11-28#about-github-notifications

These endpoints only support authentication using a personal access token (classic). For more information, see "[Managing your personal access tokens](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token)."

GitHub Apps and Fine-grained token isn't currently supported. I can see why this is misleading, I'd reach out to the relevant teams to have this docs updated to avoid confusion. The PM also mentioned this here about FPAT not currently supporting Notifications API.

Please let me know if there is anything else I can assist with.

Best,

GitHub Support

Documentation has since been updated

At least they acknowledged it and quickly fixed the docs! Sucks it wasted your time though.
