New Braze Support/Get Help Functionality

I went to go log a Support case today but noticed that the Get Help button has been updated to a premium feature where only Designated Support Contacts can access it. I'm having trouble understanding and getting this new functionality to work. Wondering if someone could help:

1. I am currently marked as a Designated Support Contact but when I try to log in to the new portal, I get an error message that tells me to contact my Support Administrator. However, I am the administrator for my company. How do I access this portal?

2. What is the limit on Designated Support Contacts? I am currently the only person checked off as a Designated Support Contact. When I tried to add other people in my company, I was told I had reached my limit. Is the limit 1 person?

3. How do people who are not Designated Support Contacts reach Braze Support?
