Add a revenue, without an invoice

As explained here https://akaunting.com/blog/getting-started-incomes, there use to be two types of incomes within Invoice and Revenue.
But I can't add revenue anymore. It was really useful, for any other non-invoicable and paid income. Have you removed that? Or am I missing something? Where can I add such a revenue?

There's still Income things, you should try that

thanks, but as stated, I know I can add Invoice. But revenue is a different thing...
