you need playerobject to teleport so it should be :Teleport(PlaceId, PlayerToTeleport). You can get all players by using a for i,v in pairs() do loop when they touch to part.
local ts = game:GetService('TeleportService')
function onTouched(hit)
if hit.Parent:FindFirstChildOfClass('Humanoid') then
for i,v in pairs(game.Players:GetChildren())do
ts:Teleport(6036609366, v)
end
end
end
script.Parent.Touched:Connect(onTouched)
