Question:
Fiware Actuator/Sensor On Off pattern with status

Description:
My configuration includes orion, IoT Agent JSON, and mongoDB.
I want to build a Fiware Lamp actuator and I want to have is on/off status (as sensor) as well.
At the moment I use a PATCH request with body (form ORION) :
At First with on command:
{
"on":

}

And then with off command:
{
"off":

}

When I receive anything from the above, I respond from the dummy device with 200 OK.
The above in my configuration makes both the on and off tags as pending:
{
"id": "urn:ngsi-ld:Lamp:001",
"type": "Lamp",
"TimeInstant": "2020-11-04T22:42:37.00Z",
"category": [
"actuator",
"sensor"
],
"controlledProperty": "lamp",
"function": [
"onOff",
"sensing"
],
"off_info": " ",
"off_status": "PENDING",
"on_info": " ",
"on_status": "PENDING",
"refStore": "urn:ngsi-ld:Store:001",
"state": " ",
"supportedProtocol": [
"JSON"
],
"supportedUnits": "My Unit 2",
"on": "",
"off": ""
}

I guess that I miss something in the way, so is there any response that I have to sent back to IoT Agent json to to make one of the two tags to stop be pending? Must I Update State or Info along the way?
P.S I expected to have a reply like this:
{
"id": "urn:ngsi-ld:Lamp:001",
"type": "Lamp",
"TimeInstant": "2020-11-04T22:42:37.00Z",
"category": [
"actuator",
"sensor"
],
"controlledProperty": "lamp",
"function": [
"onOff",
"sensing"
],
"off_info": " ",
"off_status": "PENDING",
"on_info": " ",
"on_status": "OFF",
"refStore": "urn:ngsi-ld:Store:001",
"state": " ",
"supportedProtocol": [
"JSON"
],
"supportedUnits": "My Unit 2",
"on": "",
"off": ""
}
