Using `pie-icons-webc` with the `pie-chip` icon slot

We recommend using pie-icons-webc when using the icon slot. Here is an example of how you would do this:

<!--
  Note that pie-chip and the icons that you want to use will need to be imported as components into your application.
  See the `pie-icons-webc` README for more info on importing these icons.
-->
<pie-chip>
    <icon-vegan slot="icon"></icon-vegan>
    String
</pie-chip>

Events

When the chip component is not dismissible, it does not emit any custom events. In order to add event listening to this component, you can treat it like a native HTML element in your application.

When the component is dismissible, you will need to listen to the close event listed in the table below.

Event	Type	Description
`pie-chip-close`	`CustomEvent`	Triggered when the user interacts with the close icon.
