updateMask property
Field mask used to specify the fields to be updated in the member.
If update_mask isn't provided(not set, set with empty paths, or only has "" as paths), it defaults to update all fields provided with values in the request. Using "*" as update_mask will update all fields, including deleting fields not set in the request. In case of BatchUpdate, it must be absent or the same as the update_mask in BatchUpdateMembersRequest when UpdateMemberRequest is built as a child request of BatchUpdateMembersRequest.
Optional.
Implementation
core.String? updateMask;
