Lumen help
You can store documents in Control Center that you need to manage your Lumen services—so that members of your organization can access them from a central location. When you upload a document, you can specify whether everyone in your organization can view the document or whether only users you specify can view the document. When you no longer need the document, you can delete the document. You can upload documents up to 15 MB in size and you can store up to 50 GB total per enterprise ID. You can also edit the description for a document if you need to change it later.
Note: Control Center stores General and Services documents for six months from the upload date and stores Colocation and Security documents for two years from the upload date.
