[ ADVANCED ] GUI arrow won't follow a part in workspace?

Hello, my goal is self-explanatory, have a Ui arrow point in the direction of a part that is in the workspace.

The issue is that I cannot figure out how to make the Ui arrow move freely on the Frame, it sticks to the side of the Frame, making it look "janky" by constantly teleporting around the Frame from side to side.

Here is a video example of what I am trying to achieve and what I have so far.

And here is the LocalScript which makes my version work like it does.

local Markers = {}
local Screen = script.Parent.Holder.AbsoluteSize
local T = game:GetService("TweenService")

for i,v in pairs(game.ReplicatedStorage.Markers:GetChildren()) do
    local Marker = script.Sample:Clone()
    Marker.Parent = script.Parent.Holder
    Marker.ImageColor3 = v.Config.MarkerColor.Value
    Marker.RotateLabel.Arrow.ImageColor3 = v.Config.MarkerColor.Value
    Marker.Icon.Image = v.Config.Icon.Value
    table.insert(Markers,{Marker,v})
end

function ClampMarkerToBorder(X,Y,Absolute)
    X = Screen.X - X
    Y = Screen.Y - Y

    local DistanceToXBorder = math.min(X,Screen.X-X)
    local DistanceToYBorder = math.min(Y,Screen.Y-Y)

    if DistanceToYBorder < DistanceToXBorder then 
        if Y < (Screen.Y-Y) then
            return math.clamp(X,0,Screen.X-Absolute.X),0
        else
            return math.clamp(X,0,Screen.X-Absolute.X),Screen.Y - Absolute.Y
        end
    else
        if X < (Screen.X-X) then
            return 0,math.clamp(Y,0,Screen.Y-Absolute.Y)
        else
            return Screen.X - Absolute.X,math.clamp(Y,0,Screen.Y-Absolute.Y)
        end
    end
end
