Building, integrating, or customizing apps and workflows within Microsoft Teams using developer tools and APIs
If your bot's sole purpose is to deliver notification to users and isn't conversational, you can enable the isNotificationOnly field in your app manifest. This produces the following changes:
- Users can't message your notification-only bot.
- Users can't @mention the bot.
Please follow below document for more details:
