@skjnldsv can we merge this, please? :pray:

I've tested it, it works in general. The only one thing - we should update import in Viewer.vue: import { canDownload } from '../utils/canDownload.ts'

This looks like a server issue

1. The init script is NOT added on public pages
2. Even after it is, the nc:share-attributes is empty.
