Hi,
how can I build a nested Config-object as needed in i.e. the "device" configuration variable for MQTT sensors?

I tried this

String generateConfigPayload1() {
  String deviceJSONstr = HaMqttConfigBuilder()
    .add("identifiers", "ccs811")
    .add("name", "Air Quality Sensor")
    .generatePayload();
    
  return HaMqttConfigBuilder()
    .add("device_class", "temperature")
    .add("name", "Temperature")
    .add("unique_id", "ccs811unqId_1")
    .add("state_topic", "ha/sensor/sensorBedroom/state")
    .add("unit_of_measurement", "°C")
    .add("value_template", "{{ value_json.temperature}}")
    .add("device", deviceJSONstr)
    .generatePayload();
}

but HS tells me:
Unable to parse JSON sensorBedroomT: '{"device_class":"temperature","name":"Temperature","unique_id":"ccs811unqId_1","state_topic":"ha/sensor/sensorBedroom/state","unit_of_measurement":"°C","value_template":"{{ value_json.temperature}}","device":"{"identifiers":"ccs811","name":"Air Quality Sensor"}"}'

I suspect the reason is that the nested object is inserted as a nested string "device": "{ ... }" instead of "device": { ... }
as publishing the MQTT message manually works as expected:

mosquitto_pub -t ha/sensor/sensorBedroomT/config -m '{"device_class":"temperature","name":"Temperature","unique_id":"ccs811unqId_1","state_topic":"ha/sensor/sensorBedroom/state","unit_of_measurement":"°C","value_template":"{{ value_json.temperature}}","device":{ "identifiers": "ccs811", "name": "Air Quality Sensor"}}'
