How to remove Roblox Loading Screen?

I am trying to remove the default roblox loading screen, the one that says "Joining server", I think i saw something like this on a game called "Island Royale" where it teleports you to an other place but he made his own custom gui for it.

To remove on-join, use:

--[[LocalScript in ReplicatedFirst]]
game:GetService("ReplicatedFirst"):RemoveDefaultLoadingScreen();

NOTE: This can only remove the parts **AFTER **the client is partially connecting to the server

When teleporting between places use the parameter customLoadingScreen in

TeleportService:Teleport
-- OR
TeleportService:TeleportPartyAsync
-- OR
TeleportService:TeleportToPrivateServer
-- and etc..

Thanks for reading, hope this helps!
