I fear it is time to delve a little deeper into the 'management' side of this.
Those of us with a little experience know that when (a less experienced) PF gets confused, it is pointless shouting rapid commands at him/her since, like a stall warning, they either will not register or will further confuse.
So, I ask, why did PNF ('Duty Captain') NOT take control much earlier? It is either a further indictment of AF training of their co-pilots for LHS relief (or simply for being a pilot) OR was there an extra person or persons in the flight deck that may have inhibited PNF from the firm take-over of control that was necessary? Do we know from the CVR?
