<template>
	<div>
		<button @click="showNotifcation">Toggle notification</button>
	</div>
</template>
<script>
import { useNotification } from 'vue-use-web';
import vueLogo from './logo.png'
export default {
	setup() {
		const { showNotifcation } = useNotification(
			'notification title',
			{
				icon: vueLogo,
				body: 'body of the notification',
			},
			{
				onClick: () => alert('Notification clicked'),
				onClose: () => alert('Notification closed'),
			}
		);
		return { showNotifcation };
	},
};
</script>
