Hass.agent notifier no windows notification

This is a exciting add-on I can’t wait to get working. So far all the sensors and quick keys work fine.
If I press the test send notification button it pops up a note in my win10 computer so that works. Mqtt is all connected. fire rule wall and port reg is done. Notifications for the the app are allowed in the control panel. Not errors in either Log files, HA or hass.agent… both have been restarted many times.

What could I be missing?

“Notifications: Send a notification with mypc” just does nothing.

I have similar problem.
Do we need to add anything to YAML code?
