Dimming light holding button in zigbee2mqtt

Disclaimer: I’ve tried looking for this but I couldn’t find exactly what I was after

Hi all, on zigbee2mqtt I have a fully working Tradfri 2 buttons to control a dimmable light.

I’d like not, to have a smooth dim up/down on long press.
I was looking for a ready-to-use example/blueprint to get what I want but I seem to only find zha or node-red solutions, that I cannot really use.

Is there a nice working example for this, or is anyone nice enough to provide one?

thank you
