Sign in with Google and Firebase doesn't pass the phone number of the user

Hi there,

I noticed that when I signed into my app, the phone number is not included in the users/document/collection. I can see display_name, email, and other fields I've added to the users collection. I can also see that I have a field called phone_number. Has anyone figured out how to make sure that the phone number of the user is included in the collection array?
