How can I make purchase with RevenueCat by Kotlin?

How can I make a purchase using RevenueCat v6.0.0 by Kotlin, I can see in their Docs :

Purchases.sharedInstance.purchaseWith(
  PurchaseParams.Builder(this, aPackage).build(),
  onError = { error, userCancelled -> /* No purchase */ },
  onSuccess = { storeTransaction, customerInfo ->
    if (customerInfo.entitlements["my_entitlement_identifier"]?.isActive == true) {
      // Unlock that great "pro" content
    }
  }
)

But Unfortunately I can't create this (aPackage) variable, for example if I have a product ID named: "monthly_sub", How can I get it and then pass it in this method (purchaseWith)?

I've tried to apply the docs and expect it to open Google Play paywall to make the purchase.

Bare with me, I might be missing some small thing, but one thing you could do is get your products, and use what you get back to perform the purchase:

  1. Get your products with:

    Purchases.sharedInstance.getProductsWith(
    productIds = listOf("your_product_group_id"),
    type = ProductType.SUBS,
    onError = { error ->
        // Error
    }
) { productList ->
    // Just get the first element as an example
    productList.firstOrNull()?.let {
        // You wouldn't do it this way per se, but just to show how can it be done
        performPurchase(storeProduct = it)
    }
}

  2. Perform the purchase:

    fun performPurchase(storeProduct: StoreProduct) {
    Purchases.sharedInstance.purchaseWith(
        purchaseParams = PurchaseParams.Builder(this, storeProduct).build(),
        onError = { error, userCancelled ->
            // Error
        }
    ) { purchase, customerInfo ->
        // Success
    }
}

If you need a Paywall approach I think you can also refer to this piece of code.
