Hi kaleX,
If you've completed everything up through step 5 of the guide you linked to, then an Adobe Partner Exchange rep will contact you and walk you through the rest of the process. They can help you test and ensure that you've set everything up correctly. Unfortunately, there is a bit of queue at the moment and it will probably be a few weeks before they are able to get to your project. So you may be stuck on step 5 for a bit until your project reaches the top of the queue.
Best,
Jed Madsen
