Help | Checkout Extension | To Block Postcode

Shopify Apps
1

Hi Developer,

I am trying to create a checkout extension function that would block the postcode in the checkout page.

Below is my extension code to block postcode 2022, however, it is not working/blocking.

I would really appreciate your help and information:

import {
  reactExtension,
  useBuyerJourneyIntercept,
  useShippingAddress,
  Banner,
  BlockStack,
} from "@shopify/ui-extensions-react/checkout";

export default reactExtension(
  "purchase.checkout.shipping-option-list.render-after",
  () => 

Many thanks
