getDoc
Reads the document referred to by this DocumentReference.
Note: getDoc() attempts to provide up-to-date data when possible by waiting
for data from the server, but it may return cached data or fail if you are
offline and the server cannot be reached. To specify this behavior, invoke
getDocFromCache or getDocFromServer.
