Thank you for this, could you add an async example using run_with from inside a tokio::main ?

Also, I'm quite sure the tests will fail as init_tui needs a Tokio runtime to work.

The tests ran fine locally on my machine. I only got some timeouts that didn't seem related to tokio

[LoricAndre]

You're right, I actually fixed the need for the Tokio runtime without noticing, sorry

This looks perfect, I was wondering whether this was possible or not. I'm planning a release tomorrow, so you should have this available in 3.3.0
