My preference is Pico like everyone else, but so as not to totally ignore your request, I also have one of these Aqara Opple 6 button remotes. Super reliable and very inexpensive to purchase.
There used to be an HE driver, but I'm not sure if it still works properly. I've never directly connected my Opple 6 button to HE. But if this is at your place where you just spun up HA so you could use HADB, then you can just add an inexpensive Zigbee controller. I've read that the Sonoff controller is decent, and I have never had a moment of trouble with anything connecting to my ConBee II.
It's pretty simple to create virtual switches for toggle, and auto-off virtual switches for button pressses, and then share them to HA via the HE>HA integration. Then just configure it to activate the switches in HA. I use mine for triggering my Delta VoiceIQ module. There are Blueprints for both ZHA and Z2M available, so it's super easy to setup.
