How to make player rotate relative to camera while having tool equipped and holding RMB? [closed]

I already have it so that the player can rotate relative to their movement whilst the cursor is locked to the center screen. Here's the code for that in case it is needed.

local Players = game:GetService("Players")
local ContextActionService = game:GetService("ContextActionService")
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local camera = workspace.CurrentCamera
local cameraOffset = Vector3.new(2, 2, 5)
local player = Players.LocalPlayer

player.CharacterAdded:Connect(function(character)

    local humanoid = character:WaitForChild("Humanoid")
    local rootPart = character:WaitForChild("HumanoidRootPart")
    humanoid.AutoRotate = true

    local cameraAngleX = 0
    local cameraAngleY = 0

    local function playerInput(actionName, inputState, inputObject)
        -- Calculate camera/player rotation on input change
        if inputState == Enum.UserInputState.Change then
            cameraAngleX = cameraAngleX - inputObject.Delta.X
            -- Reduce vertical mouse/touch sensitivity and clamp vertical axis
            cameraAngleY = math.clamp(cameraAngleY-inputObject.Delta.Y*0.4, -75, 75)
            -- Rotate root part CFrame by X delta

        end
    end
    ContextActionService:BindAction("PlayerInput", playerInput, false, Enum.UserInputType.MouseMovement, Enum.UserInputType.Touch)

    RunService.RenderStepped:Connect(function()
        if camera.CameraType ~= Enum.CameraType.Scriptable then
            camera.CameraType = Enum.CameraType.Scriptable
        end
        local startCFrame = CFrame.new((rootPart.CFrame.Position)) * CFrame.Angles(0, math.rad(cameraAngleX), 0) * CFrame.Angles(math.rad(cameraAngleY), 0, 0)
        local cameraCFrame = startCFrame:ToWorldSpace(CFrame.new(cameraOffset.X, cameraOffset.Y, cameraOffset.Z))
        local cameraFocus = startCFrame:ToWorldSpace(CFrame.new(cameraOffset.X, cameraOffset.Y, -10000))
        camera.CFrame = CFrame.new(cameraCFrame.Position, cameraFocus.Position)
    end)
end)

local function focusControl(actionName, inputState, inputObject)
    -- Lock and hide mouse icon on input began
    if inputState == Enum.UserInputState.Begin then
        UserInputService.MouseBehavior = Enum.MouseBehavior.LockCenter
        UserInputService.MouseIconEnabled = true
        ContextActionService:UnbindAction("FocusControl", focusControl, false, Enum.UserInputType.MouseButton1, Enum.UserInputType.Touch, Enum.UserInputType.Focus)
    end
end
ContextActionService:BindAction("FocusControl", focusControl, false, Enum.UserInputType.MouseButton1, Enum.UserInputType.Touch, Enum.UserInputType.Focus)
