I need help making the team selector

I want to create a team selection room, and after the selection is finished, I want the mini-game to begin. How can I do that? How can I distinguish the lobby from the prelobby before the map starts, then the team selection area, and finally the map itself? Thank you.

Thank you for your report! We would like to look into this further, would you be able to submit a bug report using the form available here: Fortnite Creative

You Need to set up double player spawn. In pre-lobby set First 4 spawn as Island spawn destination … in the game set other 4 spawn set as secondary. Use Island setting to add time in pre-lobby to give player time to select the team.

You find a full example in the documentation.
