import wixWindow from 'wix-window';
import {session} from 'wix-storage';

$w.onReady(function () {

	//TODO: write your page related code here...
	session.removeItem("popupPromotion")

	if (!session.getItem("popupPromotion")) {
		wixWindow.openLightbox("Announcement")
		session.setItem("popupPromotion", "yes")
	}
});

Have fun!
