Good morning guys, so i am coding a capture the flag/ control point system which is gonna to be implemented in my game, but i have ran to a problem and its making my brain a salad, which is how can i detect how many players of a certain team is in the capture radius and how many of the other are in the radius? here is my progress for the moment:

local capturePoints = game.ReplicatedStorage.CaptureProgress

local FlagPartRadius = game.Workspace.Part

local maxRadiusofCapture = 40

local capturedEvent = game.ReplicatedStorage:WaitForChild("CapturedEvent")
local sendDATA = game.ReplicatedStorage:WaitForChild("SendData")
local capturingFlag = game.ReplicatedStorage:WaitForChild("CapturingFlag")

local capturing = false

local capturers = 0
local defenders = 0 

local TeamFlag 

while wait(0.5) do
	for i, playersInTheCircle in pairs(game.Players:GetPlayers()) do
		local char = playersInTheCircle.Character or playersInTheCircle.CharacterAdded:Wait()
		local distance = (char.HumanoidRootPart.Position - FlagPartRadius.Position).Magnitude
		if distance < 40 then
			--Chequeamos si la bandera ya esta tomada o no lo esta. 					
			if TeamFlag == nil then
				--Hacemos que el equipo en el que este dicha persona ahora sea el TeamFlag
				TeamFlag = playersInTheCircle.Team.Name
				print(TeamFlag)
				capturedEvent:FireAllClients(TeamFlag)
			end
			if playersInTheCircle.Team ~= TeamFlag  then
				capturers += 1
				capturer = playersInTheCircle
				capturingFlag:FireClient(capturePoints)
				sendDATA.OnServerEvent:Connect(function()
					TeamFlag = playersInTheCircle.Team
				end)
			end
		end
	end
end

Thanks in advance!!! Hope you have a great day!

You can use Region3 for this, here is what the developer hub says about it:
