When go to the "personal settings" and scroll to "external storage", there is no button to add one. Neither when I'm logged in as the administrator nor my normal user.

You need to allow this bevore, see the documentation:

Ah, OK. Thanks. I was confused, because it says at the main screen that I have to manage that in the personal settings, so I haven't looked in the admin settings
