Describe the problem

Does netbird support tcp relay?
if I set no-udp and no-udp-relay in coturn turnserver.conf, the netbird get error

netbird status -d
Relays: 
  [stun:stunserver.stunprotocol.org:3478] is Available
  [stun:stun.freeswitch.org:3478] is Available
  [turn:turn.xx.top:3478?transport=tcp] is Unavailable, reason: allocate: Allocate error response (error 442: UDP Transport is not allowed by the TURN Server configuration)

if I set no-udp, but unset no-udp-relay in coturn turnserver.conf, the netbird status no error, but It seem that netbird client use udp to connect coturn relay :

netbird status -d
Relays: 
  [stun:stunserver.stunprotocol.org:3478] is Available
  [stun:stun.freeswitch.org:3478] is Available
  [turn:turn.xx.top:3478?transport=tcp] is Available
