Adding a new oembed endpoint in Invision 5

In Invision Community 4, we could add a hook to the \IPS\Text\Parser class to add a new oembed endpoint and this worked great. Obviously we don't have hooks in Invision 5 however.

Is there a way that I'm missing to add a new oembed endpoint?

    protected static function oembedServices()
    {
        $services = parent::oembedServices();
        $services['*.loom.com'] = array( 'https://www.loom.com/v1/oembed', static::EMBED_VIDEO );
        return $services;
    }

I realize you can add allowed iframe URLs and get a pseudo-embed that way, however it does not embed the video itself but rather a generic loom page that just has the video title. The actual oembed endpoint results in the video itself embedding.
