How to integrate svelte libraries into bud

Hello, is there any docs about how can I use modules like sveltestrap/smelte/etc inside bud app?
All I do is
```

import Button from '@smui/button';

Click me
```
and getting errors
`view: open error error=budhttp: open returned unexpected 500. budfs: open "bud/node_modules/@smui/button". ✘ [ERROR] No loader is configured for ".svelte" files: node_modules/@smui/button/dist/Button.svelte`

What additional configuration should I apply to make this?

Thank you!

Reproduce the issue in a bud app using the shown @smui/button import and inspect the reported node_modules/@smui/button/dist/Button.svelte loader error. Check how bud configures asset and module loading for Svelte dependencies. Done means the example renders without the 500 error and the required configuration is documented.
