Defining a one-to-many relation within the same table?

export const phone_call = pgTable("phone_call", {
  id: text("id").primaryKey().notNull(),
  parent_id: text("parent_id"), // if null, the this is a parent, otherwise a child call
  owner_id: varchar("owner_id", { length: 20 }).notNull(),
 //...
});

export const phoneCallRelations = relations(schema.phone_call, ({ one, many }) => ({
  owner: one(schema.user, {
    fields: [schema.phone_call.owner_id],
    references: [schema.user.id],
  }),
  parent: one(schema.phone_call, {
    fields: [schema.phone_call.parent_id],
    references: [schema.phone_call.id],
  }),
  children: many(schema.phone_call),
}));
