Creating a Floating Button that Appears on Scroll

I’m trying to implement a floating button within my viewport that becomes visible once the user scrolls to the second section (#second) and below, and then disappears again when scrolling back up to the Hero Section.

I’ve attempted to use both the “position: fixed” CSS property and a reveal-on-scroll animation with an offset. However, I’m encountering some issues with the offset functionality. Specifically, the offset doesn’t seem to work as intended, and when I set it to 9%, the button disappears entirely.

I’m seeking advice and assistance on how to correctly achieve this behavior for the floating button. Any insights or solutions would be greatly appreciated!
