Describe the bug

When enabling invoice creation in the checkout for payments, the invoices sub-collection is not created after a successful payment. It appears that this event is not currently supported by the webhook handler.

To Reproduce

1. Enable invoice creation for payments by adding the following to the checkout document:
   invoice_creation: { enabled: true }
2. Make a successful payment.

Expected behavior

I expect to have an "invoices" sub-collection within the payment document, similar to the "subscriptions" sub-collection. This would allow us to access invoice data, including the invoice PDF URL.
