Cannot ads Fibaro button

Hi, I am trying to add The Button of Fibaro directly to Homey Pro 2023. Button is working but I am not able to connect it. Following the instructions by pressing 6 times and then nothing happens. Whar can be the cause and solution. I have only 2 Zigbee devices directly connected ro Homey. One other button and one button from klikaanklikuit

If you’re not able to include the Button, so how do you know if it works?

Please have a look at this topic, maybe it’s the same problem:

Btw, I’ve returned my Button. In my opinion it’s a misconstruction, which was also more or less confirmed by the dealer.

I returned the Fibaro button. It didnt work at all.
