Hi, the scroll to feature is only available in assets like the asset flow/ carousel & flipchart. For this scroll asset, you will definitely use the move to a point or an item, if you want to show a specific item. I'm not sure what you mean by a "Then" action, but add the move command after the go to scene, you can adjust this in the timing and animation.
From your screenshot, the structure of the scroller looks a bit odd, i see a circular panel, so I'm guessing you're trying to scroll to a specific item in that, is this what you want ?
Give me a bit more detail about what you want to scroll to, I'll try and give you a solution
