Bot Framework Change form prompt message

I'm currently tying to make a formflow in C# using bot framework, here's my code so far:

[Serializable] [Template(TemplateUsage.EnumSelectOne, "Selecciona un estadio: {||}", ChoiceStyle = ChoiceStyleOptions.PerLine)] public class StadiumInfoForm { [Prompt("Selecciona un estadio: ", ChoiceFormat = "{1}")] public StadiumOptions? estadio; public static IForm<StadiumInfoForm> BuildForm() { var form = new FormBuilder<StadiumInfoForm>() .Message($"¿De qué estadio te gustaría saber?") .AddRemainingFields(); PromptAttribute title = new PromptAttribute(); List<string> quitCommands = new List<string>(); quitCommands.Add("Salir"); quitCommands.Add("Cancelar"); quitCommands.Add("No"); quitCommands.Add("Quiero salir"); quitCommands.Add("Nada"); form.Configuration.Commands[FormCommand.Quit].Terms = quitCommands.ToArray(); return form.Build(); } } 

As you can see the form will be in spanish, the problem is that the prompt displayed at the top of the form always reads "Please select an estadio", I tried changing it following this documentation but to no avail, how can I change this attribute of the form to display something like "Seleccione un estadio por favor"

I'll upload more code if needed.
