i want to create custom rule and message for it, so i write

     defineRule("required", (value) => {
       if (value === "")
         {
         return `The ${field} is required`;
         }
             return true;
           });

i want to text something for the message, as you can see, i write field, but its not the way how it works, what should i write instead of

       ${field}

to see my inputs name?
