Send message in android for one to one users

How to implement?
1

I have implemented send message event in an android project(app) from openvidu rpc protocols. The only problem is there are no docs regarding sending message from one user to another through rpc protocols, basically it broadcast message to everyone but i need to send a message to a specific connection or user.

{
“jsonrpc”: “2.0”,
“method”: “sendMessage”,
“params”: {
“message”: “{“to”:[],“data”:“Test message”,“type”:“signal:chat”}”
},
“id”: 8
}

what does parameter key “to” accepts as a value.

2

to array is an array of strings with the connection identifiers of the clients that should receive the message. For example: ["con_Xnxg19tonh","con_OV0CsFsykJ"]

Ok i will try and confirm on that. Thnks

@pabloFuente answer by fablo is correct.

You need to send connectionId in double quotes only then it is triggered to that specific user.
