The daily update is a new Windows feature that allows users to keep their Microsoft Defender virus definitions up to date.

If your Action has content that offers value every day, let users know they can get it regularly by enabling daily updates for your Action. To do so, add a registration prompt to your Action, either mid-conversation or as a suggestion chip when the conversation ends. When the user invokes one of your intents configured as a daily update, they will receive an Assistant notification at their scheduled time each day that they can tap to access your content. Make sure you offer this subscription flow in a context that makes sense to your users. Also, ensure that your daily updates are different and valuable each time they are accessed.
