when I try below to access datalayer in custom template using copyFromWindow,

`if (queryPermission('access_globals', 'readwrite', 'dataLayer')) {
     const dataLayer = copyFromWindow('dataLayer');
      log('dataLayer =', dataLayer.length);
}`

output :` `[{"gtm.start":1631682185554,"event":"gtm.js","gtm.uniqueEventId":3}]

I am trying to access say 13th item in the dataLayer array I can get the value by doing dataLayer[13].segments in console. But unable to figure out how to do this in the custom template
