Details that are there when you hover are often there in the underlying HTML. Have you checked all the element attributes of that element to see if the additional details are in an attribute you are not currenty using (you can read attributes in a read stage). Get HTML is also available to you to get the underlying HTML.
To check, try viewing the source of the HTML page in IE (i think you use developer tools for this) to see if the data exists in the underlying HTML - hopefully you will find something that looks like this:
Hover over me
Tooltip text
If not, maybe contact your Blue Prism mentor/DEM for ideas about creating code to physically hover a mouse.
