title: GA4 - Item Views by Item promotion name - no data (but promotion list shows promotions are counted)
body: <p>Im trying to setup ecommerce tracking and there is something i dont understand.
  In Google Analytics site, in reports-&gt;Monetization-&gt;Overview, there is a widget called
  &quot;<strong>Item Views by Item promotion name</strong>&quot; - I dont know why its empty.</p>
  <p>At bottom there is a &quot;view promotions list&quot; in it, and there i can see the promotions sections from my homepage are listed there. Does it count item views from the &quot;<strong>view_promotion</strong>&quot; event items, or need some promotion property in a <strong>view_item</strong> event on detail page? In both cases i set items array, where i have both item_id and item_name set - should i set item_list_name in view_items as described here?

  <p>Please provide short snippet for events needed to fill that widget with data, im lost.
  Or any idea which events and how to use for this ?</p>
  <p>(i use GA4 GTM)</p>
