Not able to find the privileged officegraphdocuments.

Hi Everyone, 

while customizing a security role to assign security role to other users, The user is getting the following error, 

RoleService::VerifyCallerPrivileges failed. User: b978e97f-e5f6-e811-a96e-000d3af069bd, PrivilegeName: prvReadOfficeGraphDocument ." 

I'm trying to assign this read privileged to the user in security role.

but im not able to find this OfficeGraphDocument privileged in security roles.  Any suggestions would be appreciated.
