What if we use UpdateDocumentAsync with empty mask?
See original GitHub issueUpdateDocumentAsync api has required parameters document and updateMask
The document just state that if any fields does not specified in the mask it would not be overridden. Which means if document already exist and we put an empty new DocumentMask() it would not write any changed field existing isn’t it?
If it behave like this, what API should we call for override everything?
