Daily update is a subscription flow that lets users receive updates from your Action at an appointed time each day. When configured, this flows appear as a notification that the user can invoke by tapping it on their Assistant device (Android and iOS).
To configure daily update for your Action, navigate to the Develop tab in the Actions console and select Scenes in the left menu. Add the daily updates system scene to your action and create an intent that will handle the update subscription flow for this scene. When prompted to subscribe, make sure that the registration prompt is given right after you show the benefit of your Action and avoid repeating the offer in other contexts. Also, keep the conversation short after the update intent is triggered to minimize the number of updates the user gets.
