Name	Type	Default	Description
autoScroll	{ buffer?: number } \| bool	true	Controls automatic scrolling to the bottom when new messages arrive or streaming content grows, as long as the user is within `buffer` pixels of the bottom. `true` – enable with the default buffer (150 px). `{ buffer: number }` – enable with a custom threshold. `false` – disable (the scroll-to-bottom affordance is still available). Scrolling when the user sends a message is always active.
