Angular app not loading css font file - asp.net core app

I'm an angular starter, and also just started test it in asp.net core (with Microsoft.AspNetCore.SpaTemplates as blogged here).

My problem is that one of my dependencies is not loading its css style, I've edit webpack.config.vendor.js to include the .css in this section:
... entry: { vendor: [ ...

The package that I have problem with is videogular which is a HTML5 video player for angular and its basic functionality works as expected, only some display features are lacking - in my specific case it's some icons on the player's component, which I thought that the vendor's config is responsible for include it. But unfortunately the Play button is not shown.
Here's the component's ts file: (excerpt)

<vg-player (onPlayerReady)="onPlayerReady($event)">
    <vg-overlay-play></vg-overlay-play>
    <vg-controls> 
        <vg-play-pause></vg-play-pause>
        <vg-playback-button></vg-playback-button>
        <vg-scrub-bar>       
            <vg-scrub-bar-current-time></vg-scrub-bar-current-time>
            <vg-scrub-bar-cue-points [vgCuePoints]="metadataTrack.cues"></vg-scrub-bar-cue-points>
        </vg-scrub-bar>

        <vg-time-display vgProperty="left" vgFormat="mm:ss"></vg-time-display>
        <vg-time-display vgProperty="total" vgFormat="mm:ss"></vg-time-display>

        <vg-mute></vg-mute>

        <vg-fullscreen></vg-fullscreen>
    </vg-controls>
    <video [vgMedia]="media" #media id="singleVideo" preload="auto">
        <source [src]="selectedAssetVideoSource" type="video/mp4">      
    </video>
</vg-player>

Solution

Sorry, turns out that running webpack --config webpack.config.vendor.js sort this out, I had no idea that it's not part of the vs build process.
