Homematic trigger channels

Recently I migrated from openhab 1.x to open 2.4. I think the new trigger channels are very useful. I created rules listening to SHORT_PRESSED and LONG_PRESSED events on these channels. In the log I can also see DOUBLE_PRESSED events. I do not see events like LONG_PRESS_RELEASED that I guess should be there. I wonder if this a configuration issue on my side or is this event type not supported by the event channel of the binding?

Any hints would be very appreciated.

I have no experience with this but I am interested because I am using homematic too.
After reading the binding documentation I think it is not supported. It is not listed as available value for the button channel.
