Minimap arrows

Hi!

I'm making a minimap for my 3D game using a top-view camera attached to the player and a rendertexture. The minimap has a circular shape and is the child of a screen-overlay canvas. The issue I'm facing is that I want to create arrows on the minimap rotating around the minimap and pointing at quest locations (something like this https://aionpowerbook.com/powerbook/Mini-Map), but I must be missing something as long as it isn't working. This is the code I'm using at the moment:

 private void Awake()
 {
     mainCamera = Camera.main.transform;
     player = GameObject.FindGameObjectWithTag("Player").transform;
 }

 private void Start () {
     transform.localPosition = Vector3.zero;
     name = name.Remove(name.Length - 7, 7);
     target = GameObject.Find("QuestLocations").transform.Find(name);
 }
 
 private void Update () {
     transform.LookAt(target.position + player.rotation * Vector3.forward, player.rotation * Vector3.up);
 }

Any ideas how to solve my problem?
