How to sort tileview by who turned on the camera

Hi,
I want to change the priority to sort tileview by who turned on the camera first.

In the config.js file, there are only role, name and hasLeft options,

 speakerStatsOrder: [
      'role', // <- Moderators on top
      'name', // <- Alphabetically by name
    //  'hasLeft', <- The ones that have left in the bottom
     ], // <- the order of the array elements determines priority

I am ready to change the source code but I don’t know where I can modify.

Good luck, guys.
Thank you
