Push message to all users

Description

It refers to sending messages with specific content, such as text, images, etc., to all online users, including the sender of the message. This feature is suitable for scenarios such as the global announcement of an event or the display of gifts across multiple rooms.

The client receives broadcast messages via the ZIM SDK callback interface and knows which user sent the message.
