Cannot use import statement outside a module when integrating Carbon Design System (Web Components) in Svelte

I'm working on a Svelte web application. The issue I'm having is when I'm trying to integrate the Carbon Web Components module. I installed the module using npm install --save @carbon/web-components — and generated the SvelteKit application using the default method (npm create svelte@latest my-app).

However, I'm encountering the following error when I try to import any component:

$ npm run build 

> my-app@0.3.0 build

Node.js v20.13.1

I understand the nature of the error, but I'm almost sure I have everything configured correctly on my end. This is how I'm using/importing the components:

// +page.svelte

<script>
  import "@carbon/web-components/es/components/accordion/index.js";
</script>

<cds-accordion>
  <cds-accordion-item title="Section Title">
    <p>
      Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
    </p>
  </cds-accordion-item>
</cds-accordion>

What else do I need to configure in the application to use ES modules with Carbon Design System components? Any help or pointers would be greatly appreciated.
