     *
     * Understanding `VisibilityTimeout`:
     *
     * - When a message is received from a queue, it becomes temporarily invisible to other consumers for the duration of
     *   the visibility timeout. This prevents multiple consumers from processing the same message simultaneously. If the
     *   message is not deleted or its visibility timeout is not extended before the timeout expires, it becomes visible
     *   again and can be retrieved by other consumers.
     * - Setting an appropriate visibility timeout is crucial. If it's too short, the message might become visible again
     *   before processing is complete, leading to duplicate processing. If it's too long, it delays the reprocessing of
     *   messages if the initial processing fails.
     * - You can adjust the visibility timeout using the `--visibility-timeout` parameter in the `receive-message` command
     *   to match the processing time required by your application.
     * - A message that isn't deleted or a message whose visibility isn't extended before the visibility timeout expires
     *   counts as a failed receive. Depending on the configuration of the queue, the message might be sent to the
     *   dead-letter queue.
     *
     * For more information, see Visibility Timeout [^1] in the *Amazon SQS Developer Guide*.

     *

    /**
     * This parameter applies only to FIFO (first-in-first-out) queues.
     *
     * The token used for deduplication of `ReceiveMessage` calls. If a networking issue occurs after a `ReceiveMessage`
     * action, and instead of a response you receive a generic error, it is possible to retry the same action with an
     * identical `ReceiveRequestAttemptId` to retrieve the same set of messages, even if their visibility timeout has not
     * yet expired.
     *
     * - You can use `ReceiveRequestAttemptId` only for 5 minutes after a `ReceiveMessage` action.
     * - When you set `FifoQueue`, a caller of the `ReceiveMessage` action can provide a `ReceiveRequestAttemptId`
     *   explicitly.
     * - It is possible to retry the `ReceiveMessage` action with the same `ReceiveRequestAttemptId` if none of the messages
     *   have been modified (deleted or had their visibility changes).
     * - During a visibility timeout, subsequent calls with the same `ReceiveRequestAttemptId` return the same messages and
     *   receipt handles. If a retry occurs within the deduplication interval, it resets the visibility timeout. For more
     *   information, see Visibility Timeout [^1] in the *Amazon SQS Developer Guide*.
     *
     *   ! If a caller of the `ReceiveMessage` action still processes messages when the visibility timeout expires and
     *   ! messages become visible, another worker consuming from the same queue can receive the same messages and therefore
     *   ! process duplicates. Also, if a consumer whose message processing time is longer than the visibility timeout tries
     *   ! to delete the processed messages, the action fails with an error.
     *   !
     *   ! To mitigate this effect, ensure that your application observes a safe threshold before the visibility timeout
     *   ! expires and extend the visibility timeout as necessary.
     *
     * - While messages with a particular `MessageGroupId` are invisible, no more messages belonging to the same
     *   `MessageGroupId` are returned until the visibility timeout expires. You can still receive messages with another
     *   `MessageGroupId` from your FIFO queue as long as they are visible.
     * - If a caller of `ReceiveMessage` can't track the `ReceiveRequestAttemptId`, no retries work until the original
     *   visibility timeout expires. As a result, delays might occur but the messages in the queue remain in a strict order.
     *
     * The maximum length of `ReceiveRequestAttemptId` is 128 characters. `ReceiveRequestAttemptId` can contain alphanumeric
     * characters (`a-z`, `A-Z`, `0-9`) and punctuation (`!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~`).
