The second argument `config` is the current configuration of this wallet. The third argument `context` is the same as in `testCreateInvoice` except it also includes `lnd` which is the return value of [`authenticatedLndGrpc`](https://github.com/alexbosworth/ln-service?tab=readme-ov-file#authenticatedlndgrpc) using the SN node credentials.
