Unable to access sku in queryProductDetailsAsync with Google Billing Library 6

I am working on migrating my project from Google Billing Library 4 to use Google Billing Library 6. In my querySkuDetails() method, I can't access the sku (string) from queryProductDetailsAsync

Here's my progress. I am not able to access skuDetails.sku, along with skuDetails.price

private fun querySkuDetails() {

    val productList =
        listOf(
            QueryProductDetailsParams.Product.newBuilder()
                .setProductId(PRODUCT_ID)
                .setProductType(BillingClient.ProductType.INAPP)
                .build()
        )

    val params = QueryProductDetailsParams.newBuilder().setProductList(productList).build()

    billingClient?.queryProductDetailsAsync(params) { billingResult, productDetailsList ->

        if (billingResult.responseCode == BillingClient.BillingResponseCode.OK) {
            for (skuDetails in productDetailsList) {
                val sku = skuDetails.sku
                if (PRODUCT_ID == sku) {
                    val price = skuDetails.price
                    priceFromBillingManager = price
                }
            }
        }


    }

}

You can replace skuDetails.sku with skuDetails.productId

As for skuDetails.price, now it depends on the product type. Since you've requested INAPP, you can find the price details inside skuDetails.oneTimePurchaseOfferDetails. The corresponding property is called formattedPrice.
