Load data on scroll up (chat like behavior)

Hello, I have used the library and it works pretty nice, however I was not able to find how to make it behave like a chat, Is there any option to load the data when the container reaches upper scroll limit?

Start by reviewing the library's existing scroll-loading behavior and documentation to determine whether reverse loading is supported. Define how reaching the upper scroll limit should request and insert older data while preserving the user's position, then document or test the resulting chat-like behavior.
