Delete a message in a channel

A user can delete any messages which were sent by themselves. An error is returned if a user attempts to delete messages sent by others. Also channel operators can delete any messages in a channel. This works the same way for both open channels and group channels.

// The MESSAGE argument below indicates a UserMessage or FileMessage object to delete.
await channel.deleteMessage(MESSAGE);

If a message is deleted, the onMessageDeleted() method in the channel event handler will be invoked on all channel participants' devices including the one that deleted the message.

const channelHandler = new OpenChannelHandler({
    onMessageDeleted: (channel: BaseChannel, message: BaseMessage) => {
        // ...
    }
});

sb.openChannel.addOpenChannelHandler(UNIQUE_HANDLER_ID, channelHandler);
