Returns true if the prompt was completed and not dismissed.
If window_id is non-null then it is used as an XWindow id on Linux. The API
expects this id to be converted to a string using the `d` printf format. The
Secret Service can make its prompt transient for the window with this id. In
some Secret Service implementations this is not possible, so the behavior
depending on this should degrade gracefully.
This method will return immediately and complete asynchronously.
