How can we access data about non-classic GitHub Projects?
The official documentation defines API resource type Project for this purpose but with this only classic Project board data can be accessed.
The new projects v2 is not in the REST api, only in GraphQL.
Check the calls in the GitHub docs here: https://docs.github.com/en/issues/planning-and-tracking-with-projects/automating-your-project/using-the-api-to-manage-projects
