How to teleport player to a point they clicked on a minimap?

I have rendered the entire map into a bird's-eye view image, and have it as an ImageButton. Here's my weak attempt at the question:

local Players = game:GetService('Players')
local localPlayer = Players.LocalPlayer
local UserInputService = game:GetService('UserInputService')
local button = localPlayer.PlayerGui:WaitForChild('Gui').Map

button .MouseButton1Click:Connect(function()
	local relativeMousePos = UserInputService:GetMouseLocation() - button.AbsolutePosition
	local pos = Vector3.new(relativeMousePos.X, 200, relativeMousePos.Y)
	print(pos)
	localPlayer.Character.HumanoidRootPart.CFrame = CFrame.new(pos)
end)

While it certainly does teleport, but neither does the scale or the position aligns with the actual map.

I have seen these posts: DevForum: 2D positioning to 3D positioning, DevForum: How would I get the world position of a GUI properly?, DevForum: How to find the cursor position inside a gui object

However I cannot understand them well enough to combine and apply them to my situation.

Original post, with an answer which did not fit the question

I don't really have a answer for the script, but I think I did manage to figure out what the devforums post means:

1. Its about how If you click on the mini-map It makes a WayPoint, and (For me using PahtFinding) a WayPoint Is a part or location placed where NPCS or Players go to, A example Is this:

local NPC = script.Parent
local PathFinding = game:GetService("PathfindingService")
local Target = game.Workspace.Location

while wait() do
	local Path = PathFinding:CreatePath()
	Path:ComputeAsync(NPC.Torso.Position, Target.Position)
	if Path.Status == Enum.PathStatus.Success then
		local Waypoints = Path:GetWaypoints()
		for i,v in pairs(Waypoints) do
			local Part = Instance.new("Part", workspace)
			Part.CanCollide = false
			Part.Anchored = true
			Part.Transparency = 1
			Part.Position = v.Position
			NPC.Humanoid:MoveTo(Part.Position)
			NPC.Humanoid.MoveToFinished:Wait()
			Part:Destroy()
		end
	end
end

1. The person Is making a GUI that Is placed In a specific spot In the mini-map which clicked created a part or location that either teleports the player there or A big arrow points down In the direction

2. The person Is trying to make a movable GUI that has a shadow below the GUI, however It appears to not move to the correct position

Hope this helps!
