Motivation / Problem statement
The package already exposes getUser(connection) for the current user.

At the moment, developers have to hand-roll a connection.sendMessagePromise({ type: "config/auth/list" }) call, which is verbose and easy to overlook. Wrapping this call in a first-class helper (parallel to getUser) will make the common pattern obvious and type-safe.

Would be a nice to have feature :)
