[Using Delphi Professional 10.2.2 with Firemonkey]

Modern vertical scrollboxes in Android/iOS apps have the abilty to look for new items if the user scrolls beyond the top of the content, or load elder items if the user scrolls beyond the end of the scrollbox content.

To implement this myself, I need an event to be fired if the user tries to scroll beyond the start or end of the scrollbox's content. How can I implement such an event with FMX.TVertScrollBox?
