You register bootstrap-vue on a throwaway app instance. That won't make it work in the component that you do that in.

You can't register plugins with Vue web components, at least not yet, without hacks.

You should however be able to use this library's components without registering the plugin by using the unplugin-vue-components plugin (which also works with webpack). Check their docs, open an issue there.
