How to see the XMPP roster in chatty?

I am used to desktop and android XMPP clients (conversations, gajim, dino) in which the client shows the XMPP roster so it is easy to click on a contact to send a message.

However, in Chatty, I can’t find that. When selecting “New message”, I see the phone contact list, most of which only has a phone number, which is very long and totally irrelevant. I would find that normal in “New SMS/MMS” but not here. Is there a way to only see the XMPP roster in chatty and not the whole contact list

that is not yet enabled in chatty.
