How to bind SWIFTUI Button action to viewmodel action or method

I am trying to bind swiftui button action and getting the error like Cannot convert value of type 'Binding<() -> ()>' to expected argument type '() -> Void'

In View

Button(action : $viewModel.action ) {
                        Text("Login")
                    }

In ViewModel

class LoginViewModel: ObservableObject {
    
    @Published var userid = ""
    @Published var password = ""
    @Published var selection : Int? = 0
    //@Published var action : () -> void = {}
    func action()  {
        
    }
    
}
