When the time comes the job is granted to Katniss.Who was Alma Coin?

Could you elaborate on the character of Alma Coin in the context of the given paragraph? The text mentions that when the time comes, the job is granted to Katniss, but then poses the question "Who was Alma Coin?" Alma Coin, from my understanding of the series, plays a pivotal role as the leader of District 13 and a key figure in the rebellion against the Capitol. Could you elaborate on how she might factor into this specific scenario where the job is given to Katniss? Does Alma Coin play a direct or indirect role in this decision? Is she supportive of Katniss or has she perhaps disagreed with her appointment? I'd appreciate a detailed explanation of Alma Coin's significance in this context.
