How to use interactive prompts with ratatui?

I want to implement a user input prompt with “inquire” (GitHub - mikaelmello/inquire: A Rust library for building interactive prompts) in a Ratatui application, ideally in a popup triggered by a key event.
Context is writing a pretty simple application for personal expenses, that allows to add new entries (e.g. “category”, “shop”, “amount” …) in a comfortable way. For this I want to have tab completion for known “shops” and so on.
I’m failing to integrate the “inquire” prompt properly into Ratatui.
