Pass data from repeating group to a popup

Need help
1

I have a repeating group which displays different users profile, I want if learn more is clicked which is in every cell for every user a popup (reusable for all users) will be shown that displays selected user’s other information.
My question is how can I get the popup populate with the selected user… I mean I don’t understand how to pass data from that cell to the popup ??

I don’t want to change page as I am building for a native app experience.

This should be fairly straightforward. Add a button to your repeating group cell.

When the button is clicked start a workflow action. For the first workflow action, use the action send data to repeating group. For the data to send, you would use the contents of this cell.

^^this assumes the cell is of data type user

Make sure the popup data type is set to user and the source is blank
