Can anyone help me position my weld script correctly?

Hello, so there is no error, because everything works perfect, but the thing is, I have not really ever used welds before, and I am needing some help positioning the CFrame of the weld in the correct position, I am making a pause menu type of thing, and I want the player to be able to hold the phone like normal, can anyone help me with the positioning?

Code:

local uis = game:GetService("UserInputService")


local plr = game.Players.LocalPlayer
local music = plr.PlayerGui:WaitForChild("MenuMusic")
local phonegui = plr.PlayerGui:WaitForChild("PhoneGui")
local char = plr.Character or plr.CharacterAdded:wait()
local hum = char:WaitForChild("Humanoid")
local hand = char:WaitForChild("LeftHand")

local cam = workspace.CurrentCamera

local phone = game:GetService("ReplicatedStorage")["Phone"]


local anim = Instance.new("Animation")
anim.AnimationId = "rbxassetid://1212301570"

local animTrack = hum:LoadAnimation(anim)

local holding = false
local spamprotect = false

uis.InputBegan:Connect(function(input, gp)
	if (gp) then
		return
	else
		if (input.UserInputType == Enum.UserInputType.Keyboard) then
			if (input.KeyCode == Enum.KeyCode.P) and (holding == false) and (spamprotect == false) then
				spamprotect = true
				
				for i,v in pairs(char:GetChildren()) do
					if v:IsA("Accessory") then
						for i,x in pairs(v:GetChildren()) do
							if x:IsA("Part") then
								x.Transparency = 1
							end
						end
					end
				end
				
				local clonedPhone = phone:Clone()
				clonedPhone.Parent = char
				clonedPhone.Position = char:WaitForChild("LeftHand").Position
				clonedPhone.CFrame = clonedPhone.CFrame * CFrame.fromEulerAnglesXYZ(0,5,0)
				local weld = Instance.new("Weld")
				weld.Part0 = hand
				weld.C0 = hand.CFrame
				weld.Part1 = clonedPhone
				weld.C1 = CFrame.fromEulerAnglesXYZ(89.6,0,-0.65) *hand.CFrame * CFrame.new(0,0,0)
				weld.Parent = clonedPhone	
				
				holding = true
				hum.WalkSpeed = 0
				hum.JumpPower = 0
				hum.MaxHealth = math.huge
				hum.Health = hum.MaxHealth
				animTrack:Play()
				wait(0.2)
				cam.CameraType = Enum.CameraType.Scriptable
				cam.CameraSubject = clonedPhone
				cam.CoordinateFrame = CFrame.new(char:WaitForChild("Head").Position, clonedPhone.Position) * CFrame.fromEulerAnglesXYZ(0,0,0)
				cam.FieldOfView = 50
				
				local blur = Instance.new("BlurEffect", cam)
				blur.Name = "Blur"
				blur.Size = 0
				for i = 0,5 do
					wait(0.05)
					blur.Size = blur.Size +1
				end
				
				phonegui.Adornee = clonedPhone
				music:Play()
				
				spamprotect = false
				
			elseif (input.KeyCode == Enum.KeyCode.P) and (holding == true) and (spamprotect == false) then
				
				spamprotect = true
				
				cam:FindFirstChild("Blur"):Destroy()
				char:FindFirstChild("Phone"):Destroy()
				holding = false
				animTrack:Stop()
				cam.CameraType = Enum.CameraType.Custom
				cam.CameraSubject = hum
				cam.FieldOfView = 70
				hum.WalkSpeed = 16
				hum.JumpPower = 50
				hum.MaxHealth = 100
				hum.Health = hum.MaxHealth
				
				music:Stop()
				
				for i,v in pairs(char:GetChildren()) do
					if v:IsA("Accessory") then
						for i,x in pairs(v:GetChildren()) do
							if x:IsA("Part") then
								x.Transparency = 0
							end
						end
					end
				end
				
				spamprotect = false
				
			end
		end
	end
end)

The weld part is all you need to worry about, I am just pasting the whole script in case you need to test it in studio if you are able to help me.
