Is there any way to use a scrollbar component with Vuetify?

I am using Vue with Vuetify and I would like to know if there is any way to change the look of the navigation-drawer scrollbar using the following component link however I do not see that it really works, it does not give me any errors in the console however I do not see the change in the appearance.

This is the code of my js input to webpack:

import Vuebar from 'vuebar'
Vue.use(Vuebar);

On my App.vue

<v-navigation-drawer
                persistent
                :mini-variant="miniVariant"
                :clipped="clipped"
                v-model="drawer"
                width="200"
                enable-resize-watcher
                fixed
                app
                dark>
            <v-list v-bar="{
                preventParentScroll: true,
                scrollThrottle: 30,
            }">
                <v-list-tile
                        exact
                        ripple
                        @click=""
                        value="true"
                        v-for="(item, i) in items"
                        :to="item.url"
                        :key="i">
                    <v-list-tile-action>
                        <v-icon v-html="item.icon"></v-icon>
                    </v-list-tile-action>
                    <v-list-tile-content>
                        <v-list-tile-title v-text="item.title"></v-list-tile-title>
                    </v-list-tile-content>
                </v-list-tile>
            </v-list>
        </v-navigation-drawer>
