First you will call inside your purchase click button

await CurrentApp.RequestProductPurchaseAsync("YourPurchase");

and inside it if its purchased you would execute inside

if (licenseInformation.ProductLicenses["YourPurchase"].IsActive)
{
}

Now you need to make sure that YourPurchase that you created inside your developer account online is running and it will be even shown inside your dashboard online along with your other published apps.
