I can't get a list of Android products (In App Purchase), how?

Question

Android

The question is more specifically to the native. I'm trying to get a list of products, but it always returns an empty array.

import * as RNIap from 'react-native-iap'

const itemSkus = Platform.select({
  android: [
    'course.level1',
    'course.level2',
  ]
})

await RNIap.initConnection()
const products = await RNIap.getProducts(itemSkus) // пустой массив

The goods have already been created and it looks like this

. If I add a predefined test product to the list of received goods android.test.purchased, then it is returned to me in an array.
PS. Today, for the first time in my life, I see the Google Play Console.
