How to send specific information from client side to Google Analytic 4 (NOT Universal)?

Question

While defining tag and triggers in Google Tag Manager, is there a way I could define that specific information from my client goes into GA4? for example I want to send the so-called store code whenever a user click on a button, so that I can understand exactly which store has had this click. The click event is not my point, I have already defined the tag and trigger, my problem is that why in the response GA4 gives me some info is missing.

in my Tag I have defined a new event with the parameter shown in photo:

Thank you in advance

Ok I found a way to send info, based on this link [GA4] Custom events which is a JavaScript code. However this is not what I was searching for because it is dependent to coding part and I wanted something which I can do from GTM

<script>
  /**
  * The following event is sent when the page loads. You could
  * wrap the event in a function to call the event when certain
  * events (e.g., a click event) happen on your site.
  */
  gtag('event', 'Your Event Name', {
    'your_param1': 'value 1',
    'your_param2': 'value 2',
  });
</script>
