Repeating group to edit users data

I am trying to build an employee database for the business owner. So I started with a repeating group.


The three-dot icon on the right. I am planning to load this users data to open in an editor that I designed with the input field like the second image below.


Now I am stuck, I don’t know how to pull out the user’s data from that repeating group to my editor. How can I know that particular raw is showing which users data.

It was my misunderstanding. I sorted it out. I just used the parent group user in the editing option.
