How to get the coordinates of Selenium Mouse cursor Python without involving any elements

I need to find a way to get location coordinates of current Selenium ActionChains invisible cursor.

I can find it after I move to an element, and calculate it from size of element and location of element, but this requires to move first to it and is not very accurate.

I can find it injecting javascript to make a div on the cursor to make it visible, and thereby even getting the location of that element, but this is not ideal because it requires that I modify the webpage’s html.

How can I achieve this?
