I'm trying to update my code with the latest PyGithub classes however documentation is missing on the new authentication methods.

jwt – string deprecated, use auth=github.Auth.AppAuth(…) or auth=github.Auth.AppAuthToken(…) instead
app_auth – github.AppAuthentication deprecated, use auth=github.Auth.AppInstallationAuth(…) instead

There isn't any documentation on:
AppAuthToken
AppInstallationAuth
