Accidentally Deleted IAM Role Admin Access on Workspace

Is there some way to contact Google Support? I am the admin for Google Workspace and I accidentally deleted all roles, so I have no roles. For example, I can create a project, but I can’t do anything else in the project (create Client IDs, etc). I can’t delete projects. I can’t even contact support (says I need to be an admin). I still have access to https://admin.google.com/ . I was trying to follow these directions, but created the wrong custom role so I tried to start over, not realizing that I was deleting access to all roles.

I apologize if I’m posting in the wrong place, with the wrong tag. I have no idea who to contact.
