Would it be possible to add an optional sound notification when a new chat message is received in Toddle? At the moment, it is easy to miss a new message when Toddle is open in a browser but is not the active tab. A subtle notification sound, with the option to enable or disable it in settings, would make real-time communication much easier for teachers and staff. Ideally, this could work similarly to other messaging platforms, while still allowing users to control the notification sound according to their preference.
