Right way to make UpdatedAt column in Drizzle?

export const users = pgTable("users", {
  id: text("id")
    .$defaultFn(() => createId())
    .primaryKey()
    .notNull(),
  kindeUserId: text("kinde_user_id").unique(),
  email: text("email").unique(),
  firstName: text("first_name"),
  lastName: text("last_name"),
  createdAt: timestamp("created_at").notNull().defaultNow(),
  updatedAt: timestamp("updated_at") // <-- HERE
    .notNull()
    .default(sql`(CURRENT_TIMESTAMP)`)
    .$onUpdate(() => sql`(CURRENT_TIMESTAMP)`),
});

export const users = pgTable("users", {

model User {
  id        Int      @id @default(autoincrement())
  name      String?
  email     String   @unique
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt // <-- HERE
}

model User {

  name      String?
  email     String   @unique
  createdAt DateTime @default(now())
