Place panel by mouse cursor and correct anchor point

I have a panel that is anchored to top left. I want to place this panel at the mouse cursor when EventTriggerType.PointerEnter (Im trying to create a hover over tooltip)

I cant get the panel to position correctly by the cursor.

Here is my code that should convert the PointerEventData.position to local space in canvas

        private void Show(BaseEventData e)
        {
            var pe = (PointerEventData)e;
            if (RectTransformUtility.ScreenPointToLocalPointInRectangle(canvas.GetComponent<RectTransform>(), pe.position, pe.pressEventCamera, out var localCursor))
                Tooltip.GetToolTip(canvas).Show(this, localCursor);
        }

And

        public void Show(ToolTipTarget tooltip, Vector2 pos)
        {
            text.text = tooltip.Text;
            gameObject.SetActive(true);

            rect.anchoredPosition = pos;
        }

The tooltip is parented directly under the canvas

Result

This was just me mixing up pivot and anchor point

LayoutRebuilder.ForceRebuildLayoutImmediate can then be used for the contet size to refresh. You can then calculate correct placement of tooltip within parent
