Looking for TURN client library recommendations

[snimavat]

Hello
New to p2p / TURN, trying to use it for following usecase

Arduino peer <-- (TCP)--> Turn server <-- turn client (Linux / Windows Host PC)-->

I am looking for a client side library that would let me connect to coturn relay.

As i understand, Arduino will need to know nothing about turn protocol, it will just connect to an allocation on turn server, the allocation would be created by turn client. And i can use turn client to communicate with arduino, coturn will act as relay in between. I believe, as there’s coturn acting as relay, i dont need to manually implement hole punching etc, I could use client to create allocation on server and communicate to peer. I can use mqtt exchange allocation information between client and arduino

Is this a correct understanding ?

I have hard time finding a suitable library - preferably nodeJs/Java/Python that i can use for coding the client side

Thanks
