Facebook Expo login fails on IOs

I’m making an application in Expo using the expo-facebook library and I don’t know why the login trying it from an IOs emulator sends me to the Expo Go login instead of that of my Facebook application when I share the code with the shared code Facebook id. Jobs when I return to the app tells me the credentials are incorrect. It just happens to me with Ios, on android I’m fine. Can you help me
