How to pass mixed stream name information between different users?

ZegoExpress SDK provides the following two methods:

• Use stream extra information: Users call the setStreamExtraInfo interface to pass in, and other users in the same room get the stream extra information by listening to the onRoomStreamExtraInfoUpdate callback.
• Use custom signaling: Call the sendCustomCommand interface to send stream name information to a specified user, and the user gets the corresponding information by listening to the onIMRecvCustomCommand callback.
