+## Sharing
+
+Click **Share** in the chat header to grant view access to other members
+of your account. You can pick individual users, a user group, or flip
+**General access** to **Organization** to make the chat visible to
+everyone. Use the **Copy link** button next to **Share** to grab a direct
+URL once access is set up. Recipients still need to have access to the
+deployment and the data the agent used; otherwise they'll see a "Chat
+not available" page.

+Recipients open the chat at the same URL as the owner and can scroll
+through the full conversation, expand the agent's reasoning and tool
+calls, and explore the charts and tables it produced — but they can't
+send new messages. Only the owner can continue the thread, and the
+header shows a "Shared by …" label so viewers always know whose
+conversation they're reading.
+
+If the owner asks more questions later, those messages — and the
+agent's replies — show up for viewers on the next load.
