transition on button without toggle or withAnimation swiftui

Question

I am trying to add a transition to a button but without using the .toggle() or withAnimation

The way that I manage the hide and show the button its with incrementing myValue.

var body: some View{
        ZStack{
             
            if(myValue>0){   //the way that I hide and show the button 
                    
                    Button {
                    
                     } label: {
                        HStack{
                         
                            Text("Button")
                                
                        }
                    }
                }
             } 
     }

How I can show and hide the Button with transition? This is not a replicate, every answer uses withAnimation or .toggle().
