App Credentials Server-To-Server OAuth

Currently, I am using 1 Pro account, and my current solution is to add 9999 basic user type accounts. However, I want to add more users to be able to share the same App Credentials Server-To-Server OAuth. What do I need to do? Do I need to purchase another license for 1 user in the user list I have already added, or is it not possible to add more and I have to use a new account?
