Can I stop shared users seeing motion notifications?

So I have a Ring Video Doorbell 4 installed. In the Ring app, I shared the doorbell with my wife and three daughters. It’s my eldest daughter’s 18th next week and we will be throwing a surprise party for her - but she has the motion notifications that pop up whenever someone’s at the door. The plan is for my wife to take her out shopping, while friends and family pile round to the house. So when they get home, we’ll all say “SURPRISE!!!” Etc. In my Ring app, I can turn off motion notifications, to try to prevent her seeing people arriving. But will she still see them, if she still has the motion notifications settings enabled on her phone?! How do I get around that?
