'How to add FirebaseUI to xcode (SwiftUI)

I am new in iOS development and trying to use firebaseUI in my project. I read documentation here:https://firebase.google.com/docs/auth/ios/firebaseui?authuser=0 but I can find anywhere in xcode that I can add firebaseUI. I did add firebase-ios-sdk, but they are no firebaseUI inside. The only one soure in firebase document said we have to add :

pod 'FirebaseUI'

But I don't know where I can add this. Please help me deal with this issue. So much appreciate any help from anyone. Thank you !
