Use DDM Manager Safari Extensions in macOS Sequoia

I'm trying to use DDM manager Safari Extensins in macOS Sequoia. I generate json and load it by mdm and ddm , but it doesn't seems to work. The json I loading is the following:

{
    "Type": "com.apple.configuration.safari.extensions.settings",
    "Payload": {
        "ManagedExtensions": {
            "*": {
                "State": "AlwaysOn",
                "PrivateBrowsing": "AlwaysOn",
                "AllowedDomains": [],
                "DeniedDomains": []
            }
        }
    },
    "Identifier": "com.test.safari"
}

macOS Sequoia response is the following:

{
  "StatusItems" : {
    "management" : {
      "declarations" : {
        "activations" : [
          {
            "active" : true,
            "identifier" : "com.example.act",
            "valid" : "valid",
            "server-token" : "5cc191206d1b1933"
          }
        ],
        "configurations" : [
          {
            "active" : true,
            "identifier" : "com.test.safari",
            "valid" : "unknown",
            "server-token" : "29d3ec5ab48e6367"
          }
        ],
        "assets" : [

        ],
        "management" : [

        ]
      }
    }
  },
  "Errors" : [

  ]
}

you can see, The "valid" value is always "unknown" at ""identifier" : "com.example.act", but "Errors" is empty, Safari app don't load extensions , the SafariExtensionSettings" ddm don't work, Is there anything wrong with "SafariExtensionSettings" json? or how can I debug this bug .
