I can't seem to find any examples or documentation on using the Beta endpoint in the @pnp/graph library. It seems there is some configuration involved looking at this PR (https://github.com/pnp/pnpjs/pull/35/commits/78995321ba4beac3a2f46e5e0b4740e541e65e80), but I can't figure out how to implement that during graph.me.get(). I need the Beta endpoint to retrieve a user's extensionAttributes. Thank you!
