How do I use MixamoAnimPack on spawnpoints

I cannot seam to find an actor but I do find spawnpoints, I cannot use the default actor in the final game obviously so I tried to use Mixamo character packs. I want to use this for a multiplayer game and randomize it so there can be different models and everyone doesn’t look the same. Unfortunately, the tutorials are outdated (UE 4.3) and do not help me as I am trying to use different characters on different spawns or better, randomize it. If someone could tell me how to fix it, that would be great. Thanks
