Retrieve a message

You can retrieve a specific message in an open or group channel by creating and passing the MessageRetrievalParams object to the getMessage() method as a parameter.

const params: MessageRetrievalParams = {
    messageId: MESSAGE_ID,
    channelType: CHANNEL_TYPE,
    channelUrl: CHANNEL_URL,
};
// ...
const message = await sb.message.getMessage(params);

You can retrieve and view the last message sent in a group channel.

const lastMessage: BaseMessage = groupChannel.lastMessage;

Depending on the type of message, cast BaseMessage to UserMessage, FileMessage, or AdminMessage to access the properties you need.
