Samsung Smart Washer and Dryer Piston Help Needed

I’m looking for a piston to have Alexa annouce washer and dryer cycle complete. I have the Samsung smart washer and dryer and they are connected through smartthings, and available in Webcore. Alexa is working to announce other events (doors opening and closing, pressence sensors, etc.) I just can’t find the right conditions to use. There’s no shortage of choices(see pic) Also don’t know which device to use. The washer and dryer each added 2 devices (washer, washer sub, dryer, and dryer sub). Any help or direction would be greatly appreciated.

Check the activity history of the device in the ST app. You should see all the status updates that ST is aware of from the device. That should point you to what to select in webcore.
