Fortnite inventory setting?

I would like to create a Zonewars map and would like to make an inventory, for example I want every player to get a gray pump, a gray assault rifle, 4 minis, 2 bigs and 1 slurpfish when starting the game, how can I adjust it with someone help, thank you ever for the answers.

It's easy

With the device team settings you can drop it in and set the settings

Thank you
