In a corporate environment, a company implements Role-Based Access Control (RBAC) to manage user permissions across various departments. The IT department has three roles: Administrator, Developer, and Support. Each role has specific permissions assigned to it. The Administrator role can create, read, update, and delete resources, while the Developer role can only read and update resources. The Support role can only read resources. If a new employee is assigned the Developer role, what is the maximum number of permissions they can have if the company decides to implement a new policy that allows for the addition of a new permission, \"Manage User Accounts,\" which can only be assigned to the Administrator role?
