How do i play event sound using WAAPI and JavaScript?

Question

 

I've tried to post events but no sound is played.

const resultId = await connection.call(ak.soundengine.postEvent, {
  gameObject: 10,
  event: "SFX",
});

The only way to get anything playing is to use transport

const { transport } = await connection.call(ak.wwise.core.transport.create, {
  object: "{987BC7F5-1F5B-467D-8FCD-DC076E39598C}" //SFX event ID
})

await connection.call(ak.wwise.core.transport.executeAction, {
  action: "play",
  transport: transport
})

Is there a simpler way? In various docs i've found reference to this statement "Posting an event will post a request to play something. This request will not be processed until the game calls the function RenderAudio();" but there is no way to call RenderAudio from JS.
