Mouaz Moustafa's IG is full of "No Name" Syrian pics. General Salim Idris is the man in the striped shirt. McCain was there to talk about weapons. He was trying to overthrow Assad so McCain was there to discuss weaponry to help. Moustafa was the middle man who arranged the meeting.
Found where Elizabeth O'Bagy said No Name and Gen. Salim Idriss met twice in Gaziantep, Turkey and crossed into Syria at the Bab Salameh border. They then had 1 meeting in Syria and I'm guessing that's where the pic with Razan Shalab Al-Sham comes in. That building has to be in close to that border crossing. Idlib, Syria was another name that kept coming up.
