Possible to use Next Experience Icons in ESC

[Vejdis]

Hello!

I'm reading through this link https://developer.servicenow.com/dev.do#!/reference/next-experience/vancouver/now-components/now-ico... and I would like to use the icons listed in the icon gallery as referenced in the api details in a widget. 

Example:

<now-icon icon="address-book-outline" size="md"></now-icon>

Is this possible to do in a portal such as /esc? Or is this only available in next experience components? Or is there some sort of prerequisite setup that I have missed

Hi @Vejdis I think it is only for next experience components. But would like to hear from experts as well.
