2. Simulate uplinks for each type of message that triggers a specific event, e.g.

APP=$1
DEV=$2

curl -i "http://localhost:1885/api/v3/as/applications/$APP/devices/$DEV/up/simulate" \
  -H "Authorization: $TTS_AUTH_TOKEN" \
  -d '{
  "downlink_ack": {
    "session_key_id": "string",
    "f_port": 0,
    "f_cnt": 0,
    "frm_payload": "string",
    "decoded_payload": {},
    "decoded_payload_warnings": [
      "string"
    ],
    "confirmed": true,
    "class_b_c": {
      "gateways": [
        {
          "gateway_ids": {
            "gateway_id": "string",
            "eui": "70B3D57ED000ABCD"
          },
          "antenna_index": 0,
          "group_index": 0
        }
      ],
      "absolute_time": "2024-08-27T08:50:56.236Z"
    },
    "priority": "LOWEST",
    "correlation_ids": [
      "string"
    ],
    "confirmed_retry": {
      "attempt": 1,
      "max_attempts": 100
