Can you tell me what the custom command for the Scan Audio Library is?

Only found this on the web

HTTP (does not work in v18 Leia)

To add new content to the library (Update):

    Video: http://<User>:<Password>@<hostname>:<port>/jsonrpc?request={"jsonrpc":"2.0","method":"VideoLibrary.Scan"}
    Audio: http://<User>:<Password>@<hostname>:<port>/jsonrpc?request={"jsonrpc":"2.0","method":"AudioLibrary.Scan"}
