要使用AWS Chime SDK-JS将与会者静音，您可以使用以下代码示例：

1. 首先，确保您已经正确安装了AWS Chime SDK-JS。可以使用npm进行安装，运行以下命令：

npm install aws-sdk
npm install aws-sdk-js

2. 在您的代码中导入所需的AWS Chime SDK模块，以及AWS SDK模块。例如：

const { ConsoleLogger, DefaultDeviceController, DefaultMeetingSession, LogLevel, MeetingSessionConfiguration } = require('amazon-chime-sdk-js');
const { ChimeClient, MuteAttendeeCommand } = require('aws-sdk');

3. 创建一个会议配置对象，并填入所需的参数。例如：

const configuration = new MeetingSessionConfiguration(meetingResponse, attendeeResponse);

4. 使用该配置对象创建一个会议会话对象。例如：

const logger = new ConsoleLogger('MyLogger', LogLevel.DEBUG);
const deviceController = new DefaultDeviceController(logger);
const meetingSession = new DefaultMeetingSession(configuration, logger, deviceController);

5. 获取要静音的与会者的attendeeId。

const attendeeIdToMute = 'attendee-id-to-mute';

6. 创建一个AWS Chime Client对象。

const chimeClient = new ChimeClient({ region: 'your-aws-region' });

7. 创建一个MuteAttendeeCommand对象，并传入与会者的attendeeId和会议的meetingId。

const muteAttendeeCommand = new MuteAttendeeCommand({
  AttendeeId: attendeeIdToMute,
  MeetingId: configuration.meetingId
});

8. 使用AWS Chime Client对象调用MuteAttendeeCommand，将与会者静音。

const muteAttendeeResponse = await chimeClient.send(muteAttendeeCommand);

完整的示例代码如下：

const { ConsoleLogger, DefaultDeviceController, DefaultMeetingSession, LogLevel, MeetingSessionConfiguration } = require('amazon-chime-sdk-js');
const { ChimeClient, MuteAttendeeCommand } = require('aws-sdk');

async function muteAttendee() {
  const meetingResponse = { ... }; // 从服务器获取的会议响应
  const attendeeResponse = { ... }; // 从服务器获取的与会者响应

  const configuration = new MeetingSessionConfiguration(meetingResponse, attendeeResponse);

  const logger = new ConsoleLogger('MyLogger', LogLevel.DEBUG);
  const deviceController = new DefaultDeviceController(logger);
  const meetingSession = new DefaultMeetingSession(configuration, logger, deviceController);

  const attendeeIdToMute = 'attendee-id-to-mute';

  const chimeClient = new ChimeClient({ region: 'your-aws-region' });

  const muteAttendeeCommand = new MuteAttendeeCommand({
    AttendeeId: attendeeIdToMute,
    MeetingId: configuration.meetingId
  });

  const muteAttendeeResponse = await chimeClient.send(muteAttendeeCommand);
}

muteAttendee();

请注意，此代码示例假设您已经从服务器上获取了会议响应和与会者响应，并且您需要将其填入MeetingSessionConfiguration对象中。您还需要将attendee-id-to-mute更改为要静音的与会者的实际attendeeId。
