What is Self-serve Portal?

@LeonidS @Alex T⚜️

I have the Streams subscription. When i click on Self-serve Portal, i get this pop-up window showing something is loading but it never does.

1. What is the self-serve for?
2. What options do i have to test the Streams module? I tried setting my own OME server but didn't have any luck making it work. Is UNA now offering a plan for Video Streaming?

Thanks
