How to watch for check_sucess of smoke sensor?

Configuration
1

I have this smoke sensor: Moes ZSS-HM-SSD01 control via MQTT | Zigbee2MQTT and it has the function to check for success. That is, I click it and it sends the check_sucess. However, it never clear this check_sucess, it stays forever unless it fails.

{
    "battery": 100,
    "battery_state": "high",
    "linkquality": 69,
    "self_test": "check_success",
    "silence": "OFF",
    "smoke": false
}

therefore I cannot check for a change in self_test. However, the MQTT message is published to Home Assistant.

What is the best way to check this? It never sends the “checking” enum value
