Here, "come together" means to work or gather together successfully and harmoniously. It can also mean the place two things join, like a road, river, or something like that. It indicates a joining of people or things and can be used to indicate such, specifically in team or group events or partnerships. Ex: The best place to water raft is where the two rivers come together. Ex: Our class came together to plan the best prom this school has ever had.
