js-libp2p browser node discovery problem？

[xiangxn]

I checked some libp2p documents and want to implement an example where a node on the browser side discovers nodes in other browsers. The browser node discovers other browser nodes through a node.js bootstrap node. I used 'kad-dht', but it seems that the browser can only receive the 'peer:discovery' event of the bootstrap node. What I want to ask is: Is my configuration incorrect, or do I need another method to achieve this? The following is my configuration code:
server config:

const options = {
    addresses: {
        listen: ['/ip4/0.0.0.0/tcp/61713/ws', "/webrtc"]
    },
    transports: [
        webSockets({
            filter: filters.all
        }),
        webRTC(),
        circuitRelayTransport()
    ],
    connectionEncrypters: [noise()],
    streamMuxers: [yamux()],
    services: {
        identify: identify(),
        relay: circuitRelayServer({
            reservations: {
                maxReservations: Infinity
            }
        }),
        dht: kadDHT({
            protocol: '/ipfs/lan/kad/1.0.0',
            peerInfoMapper: removePublicAddressesMapper,
            clientMode: false
        })
    }
}

node config:

const option = {
          addresses: {
            listen: [
              '/p2p-circuit',
              '/webrtc',
            ]
          },
          transports: [
            webSockets(),
            webRTC(),
            circuitRelayTransport()
          ],
          connectionEncrypters: [noise()],
          streamMuxers: [yamux()],
          services: {
            identify: identify(),
            dht: kadDHT({
              protocol: '/ipfs/lan/kad/1.0.0',
              peerInfoMapper: removePublicAddressesMapper,
              clientMode: true
            }),
            identifyPush: identifyPush()
          },
          connectionGater: {
            denyDialMultiaddr: () => false
          },
          peerDiscovery: [
            bootstrap({
              list: [
                '/ip4/192.168.0.106/tcp/61713/ws/p2p/12D3KooWT36TURqwnygqydMHCT4fFeHdGibgW7EwcWGaj9CEnk3h',
              ],
            })
          ],
          connectionManager: {
            maxConnections: 10,
          }
}
