Tinder Clone-Premium, need to find the element group that filters which users to display

Hello, I am using the Tinder Clone-Premium template and I need to control which users to display. Obviously the template is already doing it, but I cannot find which element group is doing it. Some element group has to be type User with Data Source of Search for Users:filtered. Can someone please tell me the name of the group element which does it? Or if it is not done by an element, then tell me the way this template uses to filter displayed users? Thanks a lot!
