Does anyone know if there are any updates coming to Figma's prototyping, particularly regarding scroll-based triggers?

I’ve been working on a large prototype to demonstrate the behavior of a sticky navigation on mobile. The idea is that the navigation disappears when scrolling down but reappears when scrolling up—showing a different version upon scroll.

I’ve managed to hack together a workaround using mouse cursor in/out triggers on desktop to create the illusion of this behaviour, but that obviously won’t work on mobile. And in a mobile-first world, that’s a big limitation.

Any help would be fantastic, Figma, any ideas or updates?
