HABApp - listen to to ChannelTriggeredEvent?

Although there exists a ChannelTriggeredEvent in HABApp I could not figure our how to create an event listener for a channel triggered event.
Has anyone an example?

Thanks,
Dominik

Do you see the corresponding event in the HABApp_events.log?
Then it’s
self.listen_event('name', callback, ChannelTriggeredEvent)
