updateSoftware returns 404

Question

I tried in graph explorer to update a test device (Poly Touch Console), model: polytc8

POST https://graph.microsoft.com/beta/teamwork/devices/{deviceid}/updateSoftware
Body:

{
    "softwareType": "teamsClient",
    "softwareVersion": "1.0.96.2023050203"
}

returns 404:

{
    "error": {
        "code": "NotFound",
        "message": "UnknownError",
        "innerError": {
            "date": "2023-05-23T09:54:15",
            "request-id": "0423d71c-a634-4205-9ef3-44d65ca4e39f",
            "client-request-id": "d9899496-81f3-5e9a-536c-7e2b721fbf72"
        }
    }
}

The device ID is valid, I can use the GET https://graph.microsoft.com/beta/teamwork/{id} to read the details.

I also tried another device, a polystudiox50, the same result.
