Uppy Dashboard options not being centered in VueJS

The options in the Uppy Dashboard when displayed are being displayed left aligned instead of it being display in center which we thought was the default behavior. Also, how can we customize the classes - '@uppy/core/dist/style.css' and '@uppy/dashboard/dist/style.css'.

Please see screenshot attached and the code used below.

enter image description here

<template>
<span>
    <slot :open="open"></slot>
        <b-modal id="bv-modal-example"  hide-footer>
            <dashboard :uppy="uppy" :plugins="['Webcam','GoogleDrive']" :props="{theme: 'dark'}" />
        </b-modal>      
</span>
</template>

<script>
import { Dashboard } from '@uppy/vue'
import '@uppy/core/dist/style.css'
import '@uppy/dashboard/dist/style.css'

import Uppy from '@uppy/core'
import Webcam from '@uppy/webcam'
import GoogleDrive from '@uppy/google-drive'   

let fileNames = []

export default{
  name: 'App',
  components: {
    Dashboard
  },
  computed: {
    uppy: () => new Uppy({restrictions: {maxFileSize: 1000000,maxNumberOfFiles:5,allowedFileTypes: ['.pdf','.docx']}}).use(
        Webcam,
        GoogleDrive, {
            target: Dashboard,
            companionUrl: 'https://companion.uppy.io/',
        }
    )
    .on('complete', (result) => {
        for( var i = 0; i < result.successful.length; i++ ) {
            console.log(result.successful[i].name)
            let fileN = {
                "name": result.successful[i].name,
                "type": result.successful[i].meta.type
            }
            fileNames.push(fileN);
        }
    })
  },
  beforeDestroy () {
    this.uppy.close()
  },
  methods:{
    open:function(){
        this.$bvModal.show('bv-modal-example')
    },
    remove(key){
        this.file.splice( key, 1 );
    }
  }
}
</script>

The above code is displayed on click of a button

<kr-file v-slot="{open}" @uploaded="create">
        <b-button pill variant="warning" @click="open()"> <i class="ion ion-md-cloud-upload 
        mr-2"></i>Upload</b-button>
</kr-file>
