Thanks for visiting the Community forum. We'd love to help.
Your Google Nest Hub supports visitor announcements for Nest Hello and other compatible doorbells. It's just that this setting is enabled on your doorbell and not on your display. If you're not seeing any settings in the Eufy app or Google Home app to turn this feature on, then this may not be available. I highly recommend you contact Eufy support and request that they make this setting available. Learn more about Visitor announcements on this support website.
Hope this answers your question.
