UseAlert returns a function you call from event handlers to present a modal alert. Call it with a title, message, and any number of actions.

func (v DeleteButton) Body(s *gova.Scope) gova.View {
    showAlert := gova.UseAlert(s)
 
    return gova.Button("Delete", func() {
        showAlert("Are you sure?", "This cannot be undone.",
            gova.AlertAction{Label: "Cancel", Style: gova.ActionCancel},
            gova.AlertAction{
                Label: "Delete",
                Style: gova.ActionDestructive,
                Action: func() {
                    performDelete()
                },
            },
        )
    })
}

An alert blocks input until an action is selected. The Action callback runs after the alert is dismissed.
