Libp2p DHT peer discovery example in JS

Question

According to Libp2p documentation DHT can be used for peer discovery.

Also, Filecoin claims that they are using libp2p Kademlia DHT for discovering peers in go.

So far I have not been able to find any working examples of how to set it up in JS.

When I specify DHT for peerDiscovery:

  modules: {
        transport: [TCP],
        streamMuxer: [MPLEX],
        connEncryption: [SECIO],
        peerDiscovery: [KadDHT],
        dht: KadDHT,
        pubsub: GossipSub,
      },

I get an error in the log:

 Error: libp2p-kad-dht requires an instance of Dialer

Can anyone help please?
