Shelly 1 Gen 4 long push with Zigbee

I want to detect a long push over Zigbee with my Shelly 1 Gen4. Switching to Zigbee firmware via Shelly webserver was smooth with firmware 1.7 (don't even bother pressing the button 5x)

Integrated in Homeassistant, I only see the on/off events, but not short/long/double push. Checking with MQTT, I only see the NotifyStatus method, but not NotifyEvent, which would be needed to determine the push type

With WIFI Shelly 1 Gen3 I see

{"src":"shellyplus1-c82e180b96a0","dst":"shellyplus1-c82e180b96a0/events","method":"NotifyEvent","params":{"ts":1756974144.28,"events":[{"component":"input:0","id":0,"event":"long_push","ts":1756974144.28}]}}

I don't receive this with Zigbee Shelly 1 Gen4

Is this not implemented yet? Any plans to add this? Or am I doing something wrong?

PS: any reason why this forum is basically German only? Ich kann auch auf deutsch schreiben falls das hilft
