我@aws-sdk/client-chime-sdk-messaging用来发出获取/发送/删除频道消息的请求

import { ChimeSDKMessagingClient, ListChannelMessagesCommand } from "@aws-sdk/client-chime-sdk-messaging";

const credentials = {
    accessKeyId: "accessKeyId",
    secretAccessKey: "secretAccessKey",
    sessionToken: "sessionToken"
};

const ChannelArn = "arn:aws:chime:us-east-1:ChannelArn";

const userArn = "arn:aws:chime:us-east-1:userArn";

const chimeClient = new ChimeSDKMessagingClient({
    region: "us-east-1",
    credentials
});

const params = {
    ChannelArn,
    MaxResults: 50,
    NextToken: null,
    ChimeBearer: userArn
};

const command = new ListChannelMessagesCommand(params);

try {
    const data = await chimeClient.send(command);
    console.log("listChannelMessages DATA ->", data);
} catch (error) {
    console.error("listChannelMessages ERROR ->", error);
}

问题：如何接收消息，或订阅事件监听器来处理收到的消息。

我曾经用and而不是amazon-chime-sdk-js来做这部分，它的工作原理是这样的：aws-sdk/clients/chimeaws-sdk@aws-sdk/client-chime-sdk-messaging

const sessionConfig = new MessagingSessionConfiguration(
  memberArm,
  null,
  endpoint,
  chime,
  AWS
);

this._session = new DefaultMessagingSession(sessionConfig, this._logger);

this._session.addObserver(this.messageObserver);
this._session.start();

而且我正在尝试减少 aws-sdk 库的大小，我认为使用新的 was-sdk-js-v3 客户端应该与以前的版本不同。

我用于聊天连接的连接示例来自amazon-chime-sdk-js
