# Open from a link

> Add one attribute to a link or button, with no JavaScript.

## data-iris-open

Add `data-iris-open` to any element. Iris catches the click, stops the default action and opens the widget.

```html title="index.html"
<a href="/support" data-iris-open>Contact support</a>

<button type="button" data-iris-open>Chat with us</button>
```

## Hide the launcher

Pass `launcher: false` to use only your own buttons. Show the unread count with the [`unread` event](/reference/events/).

```js title="index.html"
Iris.init({ appId: "app_7Hq2xK9mPz", launcher: false });
```
