Add SRC and DEST addresses for LoRa nodes

hi

is it possible to send data via LoRa to particular device by its address or ID?
I dont need to use LoRa WAN because im my network there no gateway.
I need only send data to device with specific number and be sure that only this device in this moment will receive my signal. then this device should send me answer the data (sensor data).
and this cycle will repeat for another devices.

this works for me a lot of time with another MCU based on RFM95 LoRa modules and this RadioHead library:

so it would be great if I can use the same approach with CubeCell AB01 and AB02 because I want to add in my device network new devices based on CubeCell. So I dont want to use LoRa WAN if it is possible - because I would need to change everything for my old devices…

Please advice…

upd: another words - how to add to this simple examples which send/receive (LoRaReceiver or LoRaSender) data - information about the address of device?
I would like to send/receive data and know which exactly device send the packet…

another question - is it possible to configure and use CubeCell AB01/AB02 with RadioLib library?

As can I see in this library there is something like Im looking for:

// FSK modem has built-in address filtering system
// it can be enabled by setting node address, broadcast
// address, or both
//
// to transmit packet to a particular address,
// use the following methods:
//
// radio.transmit("Hello World!", address);
// radio.startTransmit("Hello World!", address);


// set node address to 0x02
state = radio.setNodeAddress(0x02);
// set broadcast address to 0xFF
state = radio.setBroadcastAddress(0xFF);
if (state != RADIOLIB_ERR_NONE) {
  Serial.println(F("[SX1262] Unable to set address filter, code "));
  Serial.println(state);
}


// address filtering can also be disabled
// NOTE: calling this method will also erase previously set
