-- New config option [muc_mention_autocomplete_min_chars](https://conversejs.org/docs/html/configuration.html#muc-mention-autocomplete-min-chars)
   By setting this option to `false` and `view_mode` to `'embedded'`, it's now possible to
   "embed" the full app and not just a single chat. To embed just a single chat, it's now
   necessary to explicitly set `singleton` to `true`.
