{
	const observer = new MutationObserver(mutations =>
	{
		mutations.forEach(mutation =>
		{
			mutation.addedNodes.forEach(node =>

			});
		});
	});

	observer.observe(document.body, {childList: true, subtree: false});

		const script = document.createElement('script')

		script.async = true
		script.src = jivoUrl

		head.appendChild(script)
