For testing LNbits, you need to create a LNbits account first via the web interface.

By default, you can access it at `localhost:5001` (see `LNBITS_WEB_PORT` in .env.development).

After you created a wallet, you should find the invoice and admin key under `Node URL, API keys and API docs`.

> [!IMPORTANT]
>
> Since your browser is running on your host machine but the server is running inside a docker container, the server will not be able to reach LNbits with `localhost:5001` to create invoices. This makes it hard to test send+receive at the same time.
>
> For now, you need to patch the `_createInvoice` function in wallets/lnbits/server.js to always use `lnbits:5000` as the URL:
