Reverse scrolltrigger actions only when reaching again top of page

[Dennyno]

Hi, following this thread: 

Adding the "once" param fixes as suggested, but how can I reverse the animation only when scrolling and ending again to top (Y: zero) ? [or example Y-100px]

onEnterBack I guess many not work, being a fixed element that doesnt enter back nowhere and I dont undertand where to add any Y value to start reversing, as it simply stay there fixed, lol

Something like: scroll down,  with this scrubbing, once scrolled really close to the top of the dom, then reverse the timeline, but without the scrubbing.

Im stucked and I dont even know if is something doable via scrolltrigger itself.

Thanks and sorry for keep on the thread, but for a misunderstanding I closed the previous one
