Reorder Match Sections - Hook

To reorder Match sections you can use the code below.

Change sections order in the "return" statement and add it somewhere in your code (e.g.: in functions.php of your theme)

add_filter( 'anwpfl/tmpl-match/sections', 'anwp_fl_reorder_match_section' );

function anwp_fl_reorder_match_section() {
  return [
    'line_ups',
    'stats',
    'goals',
    'penalty_shootout',
    'missed_penalties',
    'substitutes',
    'missing',
    'referees',
    'video',
    'cards',
    'summary',
    'gallery',
    'latest',
  ];
}
where can i find this file to modify it?
