Custom character in UE5

Hi. I have a custom character setup in UE5 but i’d like to be able to use this character in the Valley of the ancients map.
Does anyone know how to disable all that cinematic/drone stuff at the start please? Despite adding a custom game mode, player start, and deleting the level blueprint i still somehow have to play as Echo.
I’ve also tried duplicating the level so i can setup a custom game mode/player start, but i just get an empty map.
Does anyone know how i can duplicate the map so i can add my own playerstart please?
