Reopen a past chat
Open the history menu
In the chat header, click the title (for example How can I help?) to open the list of your recent chats — newest first, each titled by your first message.
Start a new chat
Click Nuevo chat (the new-chat button in the header) to start a fresh conversation. Your previous one is saved and stays available in the history.The history is per user — you only see your own conversations. It covers the assistant chat; the create-agent wizard and the Playground are separate.
