how to buy a product?
I’m following this guide but I cannot buy my products
https://www.revenuecat.com/docs/getting-started/displaying-products
I created an offering, which has two packages, the voice has the one time purchase products from apple and google.
how do I find the voice product to buy? with the package identifier?
```
try {
const productToBuy = //how to find the product?;
if (!productToBuy) {
console.error("No product identifier found");
return;
}
```
or should I buy the package?
const { customerInfo } = await Purchases.purchasePackage(
offering.all["Voice"].availablePackages
);


I thought revenuecat was supposed to be simple
