Twitter integration

Hi I saw the video that is linked below, and I am trying to make the setup to do the lead creation through a twitter and Facebook integration, I already set both Twitter and Facebook connector settings (Id and secrets), I enabled all three modules available for each (Leads, contacts, accounts), but in the map connector fields does not appears anything, and in the manage connector search appears this error message:

Error: There are no connectors enabled that have search fields defined.

If someone could help me with that part that will improve my work a lot.
