Hi, I’m trying this on a similar case where I’m having problems, I tried the Find Children activity as you proposed but I’m having “UiPath.Core.UiElement” as results, how can I translate/convert this to work with it as a string or something similar (for example: “Access to multi-company information”)?
That’s my scrolling region:
I need to search on that field for the role line that contains the Cost Center code of the user (for example: 8115) that is stored in a variable, and, once found the line that contains the cost center code, double click on it to add it to the user roles.
With Find Chldren I obtain “UiPath.Core.UiElement” I need it to be a string where I could search for my cost center code and double click on the match line, is this possible? 
For additional info, if it can help, when I do a Get Full Text it extracts the information like this:

ROLE NAME
ROLE DESCRIPTION
150=0
ROLE NAME
ROLE DESCRIPTION
150=0
…
I need to search the cost center code on the role descriptions.
