Trying to restore photos through time machine I get a message that states: "Photos could not be modified or deleted because its required by macOS"

I am trying to restore some lost photos through time machine. When I try to restore I get a message that states: "Photos could not be modified or deleted because its required by macOS" I believe I am following the correct steps: Enter time machine, navigate to photos through applications, then select restore. Please let me know if I am not following the correct steps or if there is anything else I can do?

Thanks
