Creating object storage buckets from a limited account

I have an account which has "Full Account Access" toggled OFF.
I'd like to create Buckets from this account but I'm getting an error immediately: "You don't have permissions to create a Bucket. Please contact an account administrator for details."
I gave that account all of the global permissions (can create linodes, can create nodebalancers, …) but nothing changed.
I also noticed that there isn't a global permission for object storage.

So my question is: Is it possible to work with object storage without "Full Account Access"?
