django template cannot find included template?

The error: views: [Error (where: fromfile) in ./partials/desktop_sidebar.html | Line 21 Col 18 near './partials/desktop_sidebar.html'] unable to resolve template

main.html in ./public/layouts folder, the partial is inside another folder called partials in this folder(./partials/):

<html :class="{ 'theme-dark': dark }" x-data="data()" lang="en">
  <head>
    <meta charset="UTF-8" />

      <div class="flex flex-col flex-1 w-full">

      </div>
    </div>
    {% if withModal %} {% include "partials/modal.html" %} {% endif %}
  </body>
</html>

It seems that the include syntax is unsupported by pongo2 or there's something wrong with my initialization of the engine? I did it like this:

engine := django.New("public", ".html"))

I have a public folder like this:

public 
    -- admin
          -- assets
          -- layouts
                -- partials
    -- pub
    - admin-index.html

My intention is to separate the admin area templates with actual public templates, does this setup need an embedded filesystem instead of just plain location string?
