Field mask is used to specify the fields that the update will overwrite in an instance resource. The fields specified in the updateMask are relative to the resource, not the full request. A field will be overwritten if it is in the mask. If the user does not provide a mask, the label field will be overwritten.
This is a comma-separated list of fully qualified names of fields. Example:"user.displayName,photo".
