Checkout extension points API - useBuyerJourney

[テックギーク運営者]

Hi

I'm Ryuji, an Engineer.

I am developing a Shopify App.

I tried developing Checkout app extensions, but a useBuyerJourney hook isn't working.

https://shopify.dev/api/checkout-extensions/checkout/extension-points/api

I write the following:

const buyerJourney = useBuyerJourney(); // ユーザーの購入過程を取得するためのhook
buyerJourney.intercept({
  behavior: "allow"
})
const buyerIntercept = useBuyerJourneyIntercept(); // ユーザーの購入過程を取得するためのhook

Please teach me how to this useBuyerJourney hook.
