Changing Home Page in Thinking theme

I’m using Kirby 3 with the “Thinking” theme and I’m trying to change the home page for the site from home to blog. I’m not sure where to make the change as I keep getting syntax errors. Can someone help? The config file is as follows:

<?php

return [
    'debug' => true,
    'routes' => [
        [
            'pattern' => 'home/(:any)',
            'action'  => function () {
                return go('home');
            }
        ]
    ],
    'bnomei.robots-txt.sitemap' => 'sitemap.xml',
    'omz13.xmlsitemap' => [
        'excludeChildrenWhenTemplateIs' => ['default'],
        'disableImages' => true,
      ],
    'panel' =>[
    'install' => true
  ]
];

Yiu would better do that via the home config option

Where would I put that in the config file? Do I need to use ‘[’ brackets at all? When I put it in normally, my code editor shows a syntax error or should I just ignore that?

Inside the return array:

return [
  // some settings here
  'home' => 'blog',
];

These brackets ([]) mean it is an array.

That helps, thank you!
