From the add-on settings you can define a project role as configuration management role. It is set to none by default. Once you set this something other than None, members of this role can perform following operations even though they don't have project administration role:
- Create New Versions
- Create New Components (release/unrelease or modify version attributes if version is mapped to only one component)
- Manage Component Versions (Create, delete, release/unrelease, update description, release date)
- Manage Bundles (Create, delete, release/unrelease, modify bundle content)
- Configure Subcomponents
