How can I start multiple airplay server? #3

Hello!
Firstly, I really impressed your project and thank you :)
So I want to use it for mirroring some device concurrently.

I tried as below for starting multiple airplay server.
(I use kotlin)

AirplayServer("servername", 5003, 5004, MirrorDataConsummerImplement).start()
AirplayServer("servername2", 5103, 5104, MirrorDataConsummerImplement).start()
AirplayServer("servername3", 5203, 5204, MirrorDataConsummerImplement).start()

But I can see only one server among them on my iPhone or iPad.

Is it related with value of airPlayMDNSProps in AirPlayBonjour.java like deviceid, pk, pi?
