Friends only spawn without use of a team?

I've been trying to make a spawn that detects if a player is on your friends list, and then spawns them there if they are. I don't want to utilize teams for this, and have been having trouble without the use of teams. I was wondering if anyone could help me out with this. Thanks

local friendId = 0 --replace

local friendSpawnPos = workspace.friendSpawn.Position --replace

local isFriendsCache = setmetatable({}, {__index = function(self, i)
	self[i] = game:GetService("Players")[i]:IsFriendsWith(friendId)
	return self[i]
end})

game:GetService("Players").PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		if isFriendsCache[plr.Name] then
			char:WaitForChild"HumanoidRootPart".CFrame = CFrame.new(friendSpawnPos)
		end
	end)
end)
