What
Approving a join of an artifact page's live room now shows a disclosure: while the room is open, page events from anyone in your organization who has that page open can arrive as notifications and start turns without you present. It stops when the room is stopped, when you leave auto mode, or when the conversation or session ends.
Evidence
page events from anyone in the user's organization who has the page open, now or once it is shared, arrive here as notifications that can start turns without the user present
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
