Harrier GR.3 and the Paveway II

I read that the Harrier GR.3 Carried Paveway II bombs in the Falklands conflict. I know the GR.3 had a nose mounted laser range finder plus a marked target finder or spot tracker. Was the GR.3 also capable of designating targets it self or did it need a third party like a FAC to designate targets for it?

Thanks in advance for any useful answers.
