CIcon doesn't show icons

I’ve added a CIcon element to my page: <CIcon :name="cilListNumbered" /> Now I get the following error print and no icon on my UI:

[Vue warn]: Property or method “cilListNumbered” is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.

new Vue({

Why is that?

That’s true, sorry.

@woothu You are right. Then I would kindly ask you to complete or revise the official documentation accordingly. At its current state, it’s misleading: https://coreui.io/vue/docs/components/icon.html#cicon-api
