Hubitat Elevation supported button controller capabilities matrix

@mike.maxwell got a couple of these Osram Switch 4 button, but can't get to pair them in any way. I factory reset it with 1-4 (top-left and bottom right) pressed for 10 secs (green flashes and after 10 secs it flashes quickly then turns off). Then I pressed 2-3 (top right and bottom left) for 3 secs, blu flashing then it turns off after 5 secs. HE was in Zigbee join mode, but I received no log, empty. Tried removing battery and reset it again, but in no way HE sees this.

Any suggestion to pair it? I tried the other one, but they both act in the same way. Don't know what else to try.

Thanks for any help on this.
