Show all articles on Category page for Zendesk Guide Help Centre

Does anyone know how to get all the articles that are in the Section displaying as a list in the Category page at all?

Here's what I've got, and I'm trying to achieve the full list, similar to how Slack are doing here. 

This is my category page, which is the standard Copenhagen theme: 

<section id="main-content" class="hero">
  
  <div class="hero-inner">
    <h2 class="search_title">Help Centre</h2>
    <h2 class="visibility-hidden">{{ t 'search' }}</h2>
    <svg xmlns="http://www.w3.org/2000/svg" width="12" height="12" focusable="false" viewBox="0 0 12 12" class="search-icon" aria-hidden="true">
      <circle cx="4.5" cy="4.5" r="4" fill="none" stroke="currentColor"/>
      <path stroke="currentColor" stroke-linecap="round" d="M11 11L7.5 7.5"/>
    </svg>
    {{search submit=false instant=settings.instant_search class='search search-full' placeholder='Find anything'}}
    <div class="search_topics"><strong>Common topics:&nbsp; </strong><a href="https://xxxxxx.zendesk.com/hc/en-us/sections/360000094233">1</a>, <a href="https://xxxxxx.zendesk.com/hc/en-us/sections/360000084014">2</a>, <a href="https://xxxxxx.zendesk.com/hc/en-us/sections/360000098474">3 rights</a></div>
