Fortnite creative mode talk with Game Chat?

Hi and some friends want to do 1vs 1 on ps4 and pc, so we need the game chat. But when I start the game in creative mode, we're divided into different teams and can't hear each other anymore. Is it possible to do that in a creative way?

I know the problem.

Unfortunately, I have found no solution to it. We then always have it via Whatsapp, Skype, etc. Regulated. It was not different.
