Actionable notification not working on iWatch


Just recently added an actionable notification which sends a notification when the bathroom lights is turned on at night (since my daughter has the habit not to turn off the lights) including an action to turn the light off.
The notification is send to my iPhone and also appears on my iWatch.
On the iPhone I can execute the action and the light goes off.
On the iWatch I can execute the action but nothing happens.

Any idea why?
Do I need to configure or enable something on the iWatch or in the companion app to enable this?
