I try to get MMM-Iframe running https://github.com/alberttwong/MMM-iFrame
I tried with the code he shares on there with https://www.google.com as URL
The MagicMirror works, but the Iframe is not shown

{
	module: 'MMM-iFrame',
	position: 'bottom_bar',
	config: {
			url: ["https://www.google.com"], 
			updateInterval: 0.5 * 60 * 1000,
			width: "100%", 
			height: "100px"
		}
},

anybody knows what I do wrong?
ty for the help
