How to manually update scroll offset properly?

[algosdev]

Question:

I'm using ScrollControls and useScroll, based on scroll.offset, I'm moving camera inside useFrame. ScrollControls has pages={20}. At some point, when button is clicked, I need to manually update scroll.offset to half way (page=10), and make it possible to continue scroll from there. I've tried setting scroll.offset = 0.5, which worked. But after I start scrolling, scroll.offset goes to its previous value. I've also tried scroll.el.scrollTo method - no luck. scroll.range, scroll.curve methods seems to be not what I want (still playing with them).

Anyone knows the way?
