This is what I see in the serial console output. What is the expectation/usage of the ConsoleURI

curl -sk   "${CONSOLE_HOST}/redfish/v1/Systems/${SYSTEM_ID}"   -u "${CONSOLE_USER}:${CONSOLE_PASS}" | jq .SerialConsole
{
  "MaxConcurrentSessions": 1,
  "Oem": {
    "Intel": {
      "AMT": {
        "ControlMode": "ACM",
        "SOLStatus": "Enabled",
        "UserConsentStatus": "NotRequired"
      }
    }
  },
  "WebSocket": {
    "ConsoleURI": "/relay/webrelay.ashx?host=78563412-0009-0000-0000-000000000000&mode=sol",
    "Interactive": true,
    "ServiceEnabled": true
  }
}
