`product.variants` are not typed correctly when calling `shopify.Product.find()`

[magoz]

Issue summary

product.variants are typed as [key: string]: any when calling shopify.Product.find().

I can see that types for variants exist in the codebase, but I guess there are not inferred or applied correctly.

• @shopify/shopify-api version: 2023-04
• Node version: 18.12.1
• Operating system: MacOS 12.6.5

Expected behavior

product.variants to be typed strongly typed.

Actual behavior

const session = shopify.session.customAppSession('shop.myshopify.com')
const product = await shopify.rest.Product.find({ session, id })

if(product?.variants) {
  console.log(product.variants)
                       // ^?  (property) Product.variants: Variant[] | {
                       //          [key: string]: any;
                       //     }
}

Steps to reproduce the problem

import { shopifyApi, ApiVersion, LogSeverity } from '@shopify/shopify-api'
import { restResources } from '@shopify/shopify-api/rest/admin/2023-04'

const shopify = shopifyApi({
  apiVersion: ApiVersion.April23,
  apiSecretKey: process.env.SHOPIFY_API_SECRET_KEY ?? '',
  adminApiAccessToken: process.env.SHOPIFY_ADMIN_API_ACCESS_TOKEN ?? '',
  isCustomStoreApp: true,
  isEmbeddedApp: false,
  hostName: 'shop.myshopify.com',
  restResources
})

const session = shopify.session.customAppSession('shop.myshopify.com')
const product = await shopify.rest.Product.find({ session, id })
