Hello! Im doing some command block stuff in 26.1.2 and have run into some issues.

Im trying to make a book with a command you can press that gives the nearest person on team A blindness for 5 seconds, and then gives the person who pressed the book command (who is on team B ) blindness for 5 seconds as well. (but only after the first guys blindness has ended.)

I have no idea how to make that happen though, i tried using some detect nearest entity to player stuff with an armor stand but couldnt get it to work. any suggestions?
