Zigbee Dimmer Avatto: Physical Impulse switch - not working

Avatto: 1ch Dimmer Zigbee
Model: DMS16/ZDMS16.
Sonos USB 3 E dongle.
Jung: impulse-switch 531EU

in HA this dimmer works fine. Turn in on/off, dimmer from 5% to 99%
But i have added the impulse switch, this will turn it on or off for the time it is pushed, but when releasing the button, it turns of or on again.
In the manual it is mentioned:
short push(<1s) permanent on or off
long push (>1s) adjust the brightness/dimmer

Anyone have a solution. or same experience?

I just installed such a device today. For zigbee devices I use zigbee2mqtt. The switch type variable must be set to momentary, then it works.
