Alert in ViewModel

I am using the Acr.Dialogs as follows, to display dialog box. However, it seems it only supports one button which is OK. However, I want to have Cancel and OK buttons.

ViewModel.cs

var alertConfig = new AlertConfig
{
   Message = "Are you sure?",
   OnOk = () => {
      NotifyUpdated();
    },
};
Mvx.Resolve<IUserDialogs>().Alert(alertConfig);

Confirmation dialogs have OK and Cancel by default. You could use Task<bool> IUserDialogs.ConfirmAsync(string message, string title = null, string okText = null, string cancelText = null, CancellationToken? cancellationToken) method instead.

var confirm = await Mvx.Resolve<IUserDialogs>().ConfirmAsync("Are you sure?");
if (confirm)
{
    NotifyUpdated();
}
else
{
    // User pressed Cancel
}

If you want to keep things synchronous you could use this code:

Mvx.Resolve<IUserDialogs>().Confirm(new ConfirmConfig
{
    OnAction = b =>
    {
        if (b)
        {
            NotifyUpdated();
        }
        else
        {
            // User pressed Cancel
        }
    }
});
