Overriding Default configuration of tasklist in Camunda 7.22

As per Camunda 7 documentation, I can override the default configuration of Tasklist using a central configuration file located in app/tasklist/scripts/config.js. Where do I get this file? do I need to modify the source code of Camunda tasklist or some configuration file which I will need to place within my springboot application
I am running embedded version of Camunda 7.22.
