The pivot word while tells you that the later contributions were achieved in a manner opposite to “single-handedly.” You need two words that mean “cooperative.” Note that trap answers solitary and unilateral are the opposite of what you need, and collusive has the wrong spin — to collude is to “cooperate for illegal or fraudulent purposes.”
