Hello,
All the claims can be found here, and customizing claims mapping information can also be found in the docs here : https://learn.microsoft.com/en-us/azure/active-directory/develop/active-directory-claims-mapping
Unfortunately we don't have a document specifically for showing every single claim. It should be similar to the SAML user attributes. If you're still interested in this, please file a github issue against the docs and someone will look into it accordingly and put it in the backlog of items to do.
Thanks for your feedback.
