swift - How to do something(for example: print("hi")) in NavigationLink before moving to a destinationView

I am trying to create a button an want to do some stuff before navigating to another view. But if I use a Button, I can't navigate to another view and if I user NavigationLink, I can't do anything except navigating.

I am adding button and navigation link below.

I am trying to do firebase authentication with this button and after completing authentication I want to navigate to another view.

Button(action: {print("Hi")}) {
                Text("Create Account")
                    .font(.system(size: 20))
                    .foregroundColor(Color("GreyLabel0"))              
    }

NavigationLink(destination: WelcomeView()) {
     Text("Create Account")
                    .font(.system(size: 20))
                    .foregroundColor(Color("GreyLabel0"))
}
