how can I get the languages from a sound in Authoring API?

Question

I can't seem to construct a query that gets me the language from the object below:

I tried:

get_rqst = {
... 'uri': WAAPI_URI.ak_wwise_core_object_get,
... 'options': { "return": ['name', "@Language"] },
... 'args': {... "from": { "id": [ '{FC03083F-2AE9-4308-84DD-F18E0B364556}'] } } }

     and all I get is the name.
