I can’t choose the selector on the right bar.
Screenshot of what exactly?
Are you not able to get the selector in ui explorer?
No, i can,t indicate this selector
If it’s a web application make sure you have installed corresponding browser extension
Say if you are using chrome browser then install chrome extension from UiPath Studio → File → Tools and install extension
Only then you will be able to highlight individual element u want
If it’s a desktop application try with different UIFRAMEWORK methods
Open studio → Design tab → UI Explorer and click on UI Framework option in it
Try with different methods you have there like default, active accessibility and try indicating the element
If none of them works then try with COMPUTER VISION activity
Search computer vision in activity panel and try to use those activities
