Implementing Business Logic Validation in `Schema.TaggedClass` with Custom Validation Function

export class ProductOptionEntity extends Schema.TaggedClass<ProductOptionEntity>(
  "ProductOptionEntity",
)(
  "ProductOptionEntity",
  Schema.Struct({
    ...Struct.omit(ProductOption.fields, "id", "values"),
    id: Schema.optionalWith(ProductOptionId, {
      default: () => ProductOptionId.make(generateId()),
    }),
    values: Schema.Array(Schema.string), 
    //                   ^^^ For example, how can I make sure here these strings are not ""
  }),
) {}
