OpenEMR 5.0.2 frontend question: Which files present the patient finder

A year or two ago, I modified the patient finder with the help of another developer so that I could see the patient status in the patient finder. Now I cannot remember what the files were, and I want to copy them to another test system. The result looks as shown below (look at the extreme right-hand column). Where would I find the relevant files (.js, PHP, etc.)

OpenEMR Version
I’m using OpenEMR version v5.0.2p5

Operating System
I’m using: Ubuntu/Docker on AWS

Thank you in advance,
