How to animate transitions between child views with slide effect in SwiftUI?

I want to animate transitions between child views with slide effect but the way I do it doesn't work. How to do it right?

ContentView.swift:

struct ContentView: View {
    @EnvironmentObject var session: SessionStore
    
    var body: some View {
        Group {
            if(self.session.session != nil && (Auth.auth().currentUser?.isEmailVerified)!){
                VStack{
                Text("Welcome to the app")
                Button(action: {session.signOut()}){
                    Text("Sign Out")
                }
                }.transition(.move(edge: .trailing))
                //also I tried .transition(.slide))
            }
            
            if(self.session.session != nil && !(Auth.auth().currentUser?.isEmailVerified)!){
                EmailVerificationView()
                    .transition(.move(edge: .trailing))
            }
            
            if(self.session.session == nil){
                SignInView()
                    .transition(.move(edge: .trailing))
            }
        }.onAppear(perform: {
            session.listen()
        })  
    }
}
