I figured out how to access the hidden Employer/University status page.
First, you need to know the number associated with your webpages. So once you log-in, go to some page other than the homepage to find this. I clicked on the link under the Grad Schools list that says "Click here to update your record on schools..." and got my numbers from the end of that URL page.
Once you have your web ID numbers (mine is 5 digits), just fill them in at the end of this URL:
https://egem2.gemfellowship.org/#/fellowship/myfellowshipoverview/XXXXX
That should take you to the hidden page. I think you have to already be logged into GEM on a different tab for this to work.
Hope this helps!
Edit: The bold X's at the end are where your numbers go, they aren't included in the URL
