Privileges that will allow users to Manage Configuration Packages

Summary:

We are task to create a custom role that will allow users to Manage Implementation Project and Manage Configuration Packages via the Setup and Maintenance. We have added the following privileges and duty roles:

Manage Implementation Project
Manage Configuration Packages
Submit Import Setup Data Process
Submit Export Setup Data Process
Upload data for Functional Setup Export
Upload data for Functional Setup Import

However, when we are trying the Manage Configuration Packages functionality, we are encountering an error indicating that we do not have the required permission. Would anyone know what privileges or duty roles are missing from the custom job role?
