How do I create a scrolling animation WITHOUT using Tap trigger?

Most users do not click on a webpage to scroll down to page. They use scroll bars to wheel it down to the page and on the phone, they use their fingers to drag and scroll down the webpage. Tap trigger is to click on the entire webpage to scroll down automatically. Its weird to figure out whether or not we need to click or drag it down to the page.

The problem with the Tap trigger, it will not animate when it was scrolled down using their fingers on the phone or use the scroll bars.

Whats the best way to make it work?
