How do you find when app is in review?

How do you find when app is in review?

Apple didn’t approve my app because it had a login screen and they were asking for credentials to test what was behind that screen. So, I knew the app was on review because they log in with the credentials I gave them. I check this in the line if (!MACUSER) {}.
