set address for LoRa AS62-T20 module

you mean this ?
SoftwareSerial LoRa(2,3); // Tx, Rx
char pack = {"hellow world"};
.
.
.
void loop (){
LoRa.write(0x00);
LoRa.write(0x03);
LoRa.write(0x04);
LoRa.write(pack);
}

but this not true and I'm looking for something like this command :
LoRa.write( 00:03:04 , pack);

the function that can do this. or library with this function!!!!!!
command that can set destination channel and address like:

LoRa.setdestinationchannel(0x04);
LoRa.setdestinationaddress(0x0003);

do you understand what am I say?
actually I don't know how can I write this function or can't find a library with this functions for my module.
if you know this ,I would very appreciate of yours.
