guardian invitations for the student identified by the `student_id`, if
guardians are not enabled for the domain in question, or for other   access
errors. * `INVALID_ARGUMENT` if a `student_id` is specified, but its format

find any record of the given student or   `invitation_id`. May also be
returned if the student exists, but the   requesting user does not have
access to see that student. (guardianInvitations.get)
