Hello @NISHITHA
For Each activities has the option to save index for current row under properties.
Save this index and use it in the selector of your Click activity.
You can use the Ui Browser to look for a property that includes row/row index in your selector.
Then replace this index with the variable for index from your For Each activity.
Sometimes you have to modify the value +2 to hit the correct line in the UI.
