Need help to animate a sticky Icon to bounce when scrolling to the bottom or top page

Animate a sticky Icon to bounce when reaching bottom or top page

Hi I’m new to Webflow, so my knowledge is kinda Basic.
I have animated a safe, 1st click opens it, on 2nd it closes it.

Now i want to achieve is to implement an Icon that moves like a sticky with you on scroll but when you scrolls to the bottom or the top of the page, it bounces like a ball.

If anyone knows a solution please let me know, couldn’t find any YT tutorials on this Topic
