Does any one know if the FileStorageContainer.Manage.All possible to assign to manage the SharePoint Embedded containers? If it's not possible, what are other options to get the full list of all containers and files within each container?
Based on the Microsoft's documentation, there is the FileStorageContainer.Manage.All Graph API permission:
FileStorageContainer.Manage.All Category Application Delegated Identifier - 527b6d64-cdf5-4b8b-b336-4aa0b8ca2ce5 DisplayText - Manage all file storage containers Description - Allows the application to utilize the file storage container administration capabilities on behalf of an administrator user. AdminConsentRequired - Yes However, when I am trying to search for FileStorageContainer.Selected, it's not showing up in the list of the Graph API permissions.
I also tried directly modifying the App registration's manifest to add the API permission using the unique role GUID:
But this GUID does not seem to exist even though it's mentioned in the documentation. 
For the context, I am trying to use Graph API to generate the report on all SharePoint Embedded containers for all apps and users.
