How to add a Co-Administrator in the new Azure portal?

azure, portal

Solution

If you want go to old portal just click in bottom to "Preview" (green button) and press "take me to previous portal"

Problem

For adding a co-administrator the Howto refers to a "Hosted Services, Storage Accounts & CDN" view. But I can't find anything like this in the new portal. Does anyone know how to do this in the new portal? Is there a way to login to the old portal?
