How to implement a interface dynamically for kotlin native

For some reason, I am implementing a simple RPC framework on KotlinNative.

I need to implement interface on runtime. Below is my Code.

interface RpcProtocol {

}

open class UdpClient<T : RpcProtocol> {

    fun call(host: String, port: Int): T {
        // implement T dynamically
    }

}
// I can use it like this
interface Kademlia : RpcProtocol {

    fun ping(node: Node): Node

    fun store(node: Node)

    fun findNode() {}

    fun findValue() {}
}

fun main() {
    val client : UdpClient<Kademlia> = UdpClient()
    val node = client.call("123", 1)
        .ping(Node(Id.createByPow(2), "123", 1))
}

Can anyone help me, than very much
