What i have is 4 different streams and in one of the streams i have 5 users access this stream, this app has 5 sheets, I want only 1 user out of these 5 users to see sheet5 including the other 4 , and the other 4 users can see only the other 4 sheets .
but the problem I am facing is; when I apply the User1 to see Sheet5 in the security rule, it either hides all from all other users including all other streams or it shows all sheets to all users.
