How to check if player id is in an array?

Hi, I'm making an anti-cheat and I want to have users who are ignored in the anti-cheat, I have ID's in an array and I just need to check if a player id is in the array. I currently have

local AdminIDS = {109811710} -- My ID

game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		local Character = player.Character
		local RootPart = Character.HumanoidRootPart
		
		while wait() do
			--Speed Detection--
			local Pos1 = RootPart.Position
			wait()
			local Pos2 = RootPart.Position
			local difference = ((Pos1 - Pos2) * Vector3.new(1, 0, 1)).Magnitude -- for speed hacking
			local Ydifference = ((Pos1 - Pos2) * Vector3.new(0, 1 ,0 )).Magnitude -- For jump hacking maybe

			if difference > 1.7 then -- checks if the user moved too much
				RootPart.Position = Pos1
			end
		end
	end)
end)

I want to check if the player.UserId is in the AdminIDS table, I have tried if has_value(AdminIDS, player.UserId) but that function doesn't exist. Any help is greatly appreciated

local AdminIDS = {109811710} -- My ID
local function CheckIfAdmin(UserID)
 	--Loops through each item in array and checks if the Plr UserID Matches one of the items in the array
	for _,v in pairs(AdminIDS) do
		if v == UserID then
			return true
		end
	end
	--Since nothing was returned it returns false
	return false
end

local IsAdmin = CheckIfAdmin(player.UserId)
if IsAdmin == true then
	print(player .. " Is an admin")
elseif IsAdmin == false then
	print(player .. " Is not an admin")
end
