Create a script inside of ServerScriptService and put this code into it:

01local pathfindingService = game:GetService("PathfindingService")
02local pointModel = Instance.new("Model")
03pointModel.Name = "Points"
04pointModel.Parent = game.Workspace
05 
06-- Setup remote function
07local remoteFunction = Instance.new("RemoteFunction")
08remoteFunction.Parent = game.ReplicatedStorage
09 
10function visualizePath(path)
11    -- clear old path visualization
12    for _, point in pairs(pointModel:GetChildren()) do
13        point:Destroy()
14    end
15 
16    -- calculate new visualization  
17    local points = path:GetPointCoordinates()
18    for _, point in pairs(points) do
19        local part = Instance.new("Part")
20        part.Parent = pointModel
21        part.FormFactor = Enum.FormFactor.Custom
22        part.Size = Vector3.new(1,1,1)
23        part.Position = point
24        part.Anchored = true
25        part.CanCollide = false
26    end
27end
28 
29game.ReplicatedStorage.RemoteFunction.OnServerInvoke = function(player, target)
30    local start = player.Character.Torso.Position
31    local path = pathfindingService:ComputeRawPathAsync(start, target, 500)
32 
33    visualizePath(path)
34    -- Check to see if the path was computed correctly
35    if path.Status == Enum.PathStatus.FailStartNotEmpty or path.Status == Enum.PathStatus.FailFinishNotEmpty then
36        print("Compute failed")
37        return {}
38    end
39 
40    return path:GetPointCoordinates()       
41end

Then make a Local Script and put it into Starter Pack and put this code in it:

01local player = game.Players.LocalPlayer
02local mouse = player:GetMouse()
03 
04local followingPath = false
05mouse.Button1Down:connect(function()
06    if not followingPath then
07        followingPath = true
08 
09        -- Ask the server to calculate a path for us
10        local points = game.ReplicatedStorage.RemoteFunction:InvokeServer(mouse.Hit.p)
11 
12        for _, point in pairs(points) do
13            print("moving to: ", point)
14            player.Character.Humanoid:MoveTo(point)
15            -- Don't try moving to the next point until we are close enough to the current point in the path
16            repeat
17                distance = (point - player.Character.Torso.Position).magnitude
18                wait()
19            until distance < 3
20        end
21        followingPath = false
22    end
23end)
