 The options object is optional and accept the following properties:
 - `keepMessages` (boolean): To avoid deleting the message after processing it. Default is `false`.

+- `messageAttributesNames` (string array): The value which will be sent to the `receiveMessage` SQS method at the `MessageAttributeNames` property. Default value is `['All']`.
 
 After the handler returns (if it returns a Promise, SQS Quooler will wait for it to resolve), the item is automatically deleted from the queue. If your handler throws an error, or returns a rejected Promise, the item will not be removed from the queue.
