RoomMessageReviewEventSource

Source: src/AWS/Lambda/RoomMessageReviewEventSource.ts

Connects an IVS Chat room’s message review handler to the current Lambda function.

At deploy time this layer injects the function ARN into the room’s messageReviewHandler through the room’s binding contract and materializes the lambda:InvokeFunction Permission for ivschat.amazonaws.com; at runtime it dispatches review invocations (matched on RoomArn) to the registered handler and returns the verdict to IVS Chat.

      : undefined,
  ),
);
