There is no pre-defined activity for finding the same in a single step.

But still you can build logic for the same using system activities.

Do you have that logic already in any programming language ?

Or you want to build it from scratch.

YES, I worked for some Programming Languages : C, Java, Python…etc. but when it comes to UiPath Sometimes there is some Activities to build the same that Probably I don’t Know.

If you can share logic I can help you with building in UiPath.
