The Scroll Indicator is a variation on the Scrollbar. It is not intended for direct interaction, but rather to display the current scroll position of the linked Scroll Rect.
This prefab uses a custom
Scroll Indicator component, that while it has similar options to the Scrollbar component, is a different class and contains a reference to the Scroll Rect as opposed to the reversed relationship of the Scrollbar.
