As an admin I want to see user notebook links, so that I can easily go to users Notebook by demand.
Notebook links are portrayed only for own resources. Administrator does not know the Notebook link of other user.
So convey notebook links to administrator in 'Environment management' page:
- Administrator can view links of another user
- User is not able to view links of the other user
