        - `DownlinkMode` 'SEQUENTIAL' | 'CONCURRENT' | 'USING_UPLINK_GATEWAY', required — Indicates whether to send the downlink message in sequential mode or concurrent mode, or to use only the chosen gateways from the previous uplink message transmission.
        - `GatewayList` GatewayListItem[], required — The list of gateways that you want to use for sending the downlink data traffic.
          - `GatewayId` string, required — The ID of the wireless gateways that you want to add to the list of gateways when sending downlink messages.
          - `DownlinkFrequency` integer, required — The frequency to use for the gateways when sending a downlink message to the wireless device.
        - `TransmissionInterval` integer, required — The duration of time for which AWS IoT Core for LoRaWAN will wait before transmitting the payload to the next gateway.
