How to track a world object in a Screen Space - Camera Canvas

Question

So I've seen many answers for people who want to track objects with 1 camera only set to Screen Space - Overlay, but I have not seen a single question for the case when there are several cameras at the same time (split screen), each one with it's own canvas set to Screen Space - Camera, instead of Overlay. The problem only appears with Screen Space - Camera, as I've tried with Overlay and it works perfectly.

What I do is convert the world position of an object to screen position through one of these canvas cameras, then I've tried anything I could think of, from setting the UI item position directly to the screen position, to using "ScreenPointToLocalPointInRectangle" or even WorldToViewportPoint.

Nothing worked. I desperately need some help, I've been working on this for 2 days now.

         Vector3 screenPoint = myCamera.WorldToScreenPoint(myObjectTransform.position);  
         Vector2 result;
         result = screenPoint;
         //result = myCamera.ScreenToWorldPoint(screenPoint);
         transform.position = result;

This code is inside the tracking UI object.

Hi, you can use:

 RectTransformUtility.WorldToScreenPoint(Camera.main, target.transform.position);

And what do I do after that?

After some testing, I still can't figure anything out. I feel like this is the same thing I used just with a different name.
