How include relay in circuit-relaying?

1

I want to set up circuit-relaying.
I looked at an example https://github.com/ipfs/js-ipfs/tree/master/examples/circuit-relaying

But it didn’t work for me.

When I start daemon I see the following.

js-ipfs version: 0.48.1
System version: x64 / linux
Node.js version: 13.11.0
Swarm listening on /ip4/127.0.0.1/tcp/4002/p2p/QmYnyhZ9MiGagL2juEf7DGthNG76kbRUmVMA4Ktf83SCKm
Swarm listening on /ip4/192.168.100.3/tcp/4002/p2p/QmYnyhZ9MiGagL2juEf7DGthNG76kbRUmVMA4Ktf83SCKm
Swarm listening on /ip4/127.0.0.1/tcp/4003/ws/p2p/QmYnyhZ9MiGagL2juEf7DGthNG76kbRUmVMA4Ktf83SCKm
API listening on /ip4/127.0.0.1/tcp/7070/http
Gateway (read only) listening on /ip4/127.0.0.1/tcp/9090/http

Daemon is ready

How can I enable circuit-relaying or auto relay in the config?

This config doesn’t work

  "relay": {
    "enabled": true,
    "hop": {
      "enabled": true
    }
  }
