Floating back to button

Can anyone tell me how to make this button like it has to be pop on to the screen when we scroll to the bottom and it stays there until we get to the bottom. And when ever we press on this button scrolls to the top but when the home or top screen hits the button should go invisible or hide somehow.

Anyone know how to make this? I tried my best using sticky and fixed and other methods so can anyone mention any of them with an example file attached it will be appreciated. Let me know please!

Hi there,

Thanks for reaching out. I believe smart animate will enable to achieve the goal. I tried to create a file, but I found this YouTube video clearly explaining how to do it: https://www.youtube.com/watch?v=7wL_ZcX_jW0

I hope it helps, but if you have any questions, feel free to add your comments!

Thanks,
Toku
