Following up because it took me a while to figure out.

You use the iCloud album id as a config item.
source: “icloud:”,
The album id is simply the last bit in your iCloud shared album URL. It will look something like this:
https://www.icloud.com/sharedalbum/#nUm83r5N13t+3r5
That’s not a real link, just an example.
Copy everything to the right of the #, basically nUm83r5N13t+3r5.
You must use a shared album and you have to set it to Public Website (anyone with the link can view the photos). That will allow you to generate the link. See: https://support.apple.com/en-us/108314
This is what a basic config will look like.
modules: [
{
module: "MMM-Wallpaper",
position: "fullscreen_below",
config: { // See "Configuration options" for more information.
source: "icloud:nUm83r5N13t+3r5",
slideInterval: 60 * 1000 // Change slides every minute
}
}
