Introduction
Add receiving new message callback
If logged in, ImSDK will retrieve messages send to you. PS. It doesn't have to be the unread messages
Only messages that aren't stored in the local storage will be retrieved. (Eg. Message read from other platform, and retrieve latest conversation's last message, if it's not in the local storage, the message will appear in here)
