Well, I couldn’t get Kubicki’s Smart App to work either, but I didn’t try too hard because the IFTTT setup is super easy. Got it going, thanks @rcrosier!
Edit: I actually have this triggering a simulated motion sensor, not a switch, so I can use it for Smart Home Monitor and other alert-type things. The camera/Blue Iris combo handles outdoor motion much better than anything else I’ve tried. I couldn’t find any Simulated Switch + Motion device type handlers, so I just whipped this one up:

Hope it helps.
