Photos on MacBook Pro won't show on Apple TV

I have 2021 MacBook Pro. I copy/pasted my photo file from my old Mac to new MacBook Pro. the file is around 825GB. I am also using the Apple TV 4K. I have both connected to the same wifi network. I set up Home Sharing on the MacBook and checked to box to share photos with Apple TV. In the the photos app in preferences I set the photo file as the system file. In the Apple TV, when I go to the app to view the shared media; music and movies show up, but when I select the photos tab I get a message that there are no photos in my library. The photos app on my Macbook shows all of the photos. 169,354 photos, and 7,911 videos, but they aren't sharing to my Apple TV. I was counting on the new MacBook to be able to share photos to my Apple TV. Can anyone suggest anything ? Thanks in advance..
