How include relay in circuit-relaying?

I want to set up circuit-relaying.
I looked at an example

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/
Swarm listening on /ip4/
Swarm listening on /ip4/
API listening on /ip4/
Gateway (read only) listening on /ip4/

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
