I've been poking around the Global Announcements API, and while I can post announcements for specific roles (as an admin), I cannot seem to pull the information for a specific announcement (or even when pulling all announcements) if I am not in that role.

Going to the account page in the UI, I can see all the announcements, regardless of the role set. Surely there is a way for the admin to be able to pull all announcements, regardless of the  account_notification_roles set?
