I want to create an IPFS relay v2 node using kubo (latest)

I tried setting Swarm.RelayService.Enabled to true and added “/ip4/”, “/ip6/::/tcp/4002/ws”, in Addresses.Swam.

I am trying to connect my js-ipfs (browser-based) to this node using this config

 config: {
                Addresses: {
                    API: '/ip4/',
                    Swarm: ['/ip4/<PEER_ID>/p2p-circuit'],
                    Gateway: '/ip4/'

But it’s not able to connect it shows this error Error: Transport (Circuit) could not listen on any available address
btw if I use the WebRTC-Star signaling server with the same configuration (in Swarm), it works.

What I am doing wrong?
