NavigationLink and CustomStyle BackButton

Hi Guys,

sorry if I am writing some nonsense, but I am just starting to create apps in Swift. I'm creating an app just for AppleWatch and I don't want to use the default backbutton that appears with navigationLink. How can I change the appearance? I'll put a diagram of my code here:

NavigationStack {
            VStack {
                
                NavigationLink(...) {
                   
                        HStack {
                           ...
                        }
                    
                
                }
                    .buttonStyle(PlainButtonStyle())
                    .frame(height: 80)
                    .foregroundColor(.black)
                    .fontWeight(.bold)
                    .tracking(-0.5)

            }
            
        }
        

Everything I find on the Internet is for navigationView which I read is deprecated. I found again on google a site that recommends using .toolbar, but the button does not change. What am I doing wrong? What can I do? Thanks
