3D Compass in Hololens

Question

I'm trying to develop a simple 3D Compass for Hololens 2, using Unity, but my sprites aren't aligned with the Cubes.

I wanted it to be like this: https://www.youtube.com/watch?v=3RuOq9ldX9g

If I move the cubes, the compass works as intended, but it still doesn't align with my FOV.

My code for getting the position on the compass is the following:

    Vector2 GetPosOnCompass(QuestMarker marker)
{
    Vector2 playerPos = new Vector2(Player.transform.position.x, Player.transform.position.z);
    Vector2 playerFwd = new Vector2(Player.transform.forward.x, Player.transform.forward.z);

    float angle = Vector2.SignedAngle(marker.position - playerPos, playerFwd);

    return new Vector2(compassUnit * angle, 0f);
}

Best regards,

Carlos
