Hi @Quentin_Saubadu, Thanks for reaching out about the prototype trigger. I appreciate you sharing the helpful screenshots!
Currently, creating any action triggered “while scrolling” might be a bit challenging.
You might already be aware, but this article provides detailed information on our prototyping triggers: Prototype triggers
Although not ideal, one approach you could try is connecting “Opened” and “Closed” with smart animate using the “on drag” trigger.
For more information, you can refer to this article: Smart animate layers between frames
It looks like what you’re searching for is connected to a popular idea from another community member here: “On Scroll” for prototyping
Please feel free to take a look!
I hope this helps clarify things a bit. If anyone in our community has suggestions to share, please feel free to join this conversation!
Thanks,
