updateMask property
Top-level field mask used to specify the fields to be updated in the member for all UpdateMemberRequests.
There are 4 possible scenarios for top-level and child field mask: 1. top-level and child field mask is absent: All fields provided in the requests are updated, including deleting fields not set in the requests. 2. top-level field mask is present but child field mask is absent: The fields specified in the top-level field mask are updated. 3. top-level and child field mask is present: The child field mask must be the same as the top-level field mask. 4. top-level field mask is absent but child field mask is present: It isn't supported and will return an error.
Optional.
