How to Make DHT Work in the Browser?

Users and Developers js

I am learning libp2p examples and have been experimenting on my own.
I started a relay server in a Node.js environment, along with two regular nodes, configuring the address of the relay server as the bootstrap address.

The relay server can discover both nodes, but The CID obtained after Node 1 adds data cannot be used to retrieve data in Node 2. and Node 2 can’t find Node 1 based on its peer ID.

I’m not sure what to do next. Did I miss something?

Implementation of relay:

const relay = await createLibp2p({
    privateKey: privateKeyFromRaw(privateKeyRaw),
    addresses: {
        listen: ['/ip4/127.0.0.1/tcp/54321/ws']
    },
    transports: [
        webSockets({
            filter: filters.all
        })
    ],
    connectionEncrypters: [noise()],
    streamMuxers: [yamux()],
    services: {
        dht: kadDHT({
          clientMode: false
        }),
        identify: identify(),
        relay: circuitRelayServer({
            reservations: {
                maxReservations: Infinity
            }
        })
    }
})

Node 1 and Node 2 Implementation:

const libp2p = await createLibp2p({
    privateKey: privateKeyFromRaw(privateKeyRaw),
    addresses: {
        listen: [
            '/p2p-circuit',
            '/webrtc'
        ],
        // announce: [
        //     '/ip4/127.0.0.1/tcp/54321/ws/p2p/12D3KooWGMYMmN1RGUYjWaSV6P3XtnBjwnosnJGNMnttfVCRnd6g/p2p-circuit/webrtc'
        // ]
    },
    transports: [
        webSockets({
            filter: filters.all
        }),
        webRTC(),
        circuitRelayTransport({
            discoverRelays: 1
        })
    ],
    connectionEncrypters: [noise()],
    streamMuxers: [yamux()],
    connectionGater: {
        denyDialMultiaddr: () => {
            return false
        }
    },
    services: {
        dht: kadDHT(),
        identify: identify(),
        identifyPush: identifyPush({runOnSelfUpdate: true}),
        ping: ping()
    },
    peerDiscovery: [
        bootstrap({
            list: [
                // address of relay
                '/ip4/127.0.0.1/tcp/54321/ws/p2p/12D3KooWGMYMmN1RGUYjWaSV6P3XtnBjwnosnJGNMnttfVCRnd6g'
            ]
        })
    ]
})
