One last question:
Is there no way to retrieve the user’s phone number without using the People API? If the user has consented to sharing their phone number, I’m confused on why Google forces us to query the People API for it and prevents us from retrieving it if it’s not public. If this is explained by Google’s stringent data protection practices, that’s fine, but just want to make sure there aren’t any other solutions that could provide better coverage (as I’d imagine the number of users that purposely set their phone number visibility to public is fairly low)
