It’s already initialized. The UI you see is an abstraction layer over the client/instance. All you need to do is fill the proper fields, and it will work 
It takes the same arguments as the client, it’s just a no-code layer that abstracts code into some fields/selects. The only thing you need to set up also, are the credentials in the Plugin’s settings, but you probably already did this when you installed it anyway.
