Installation of the smart Xiao Mi Aqara switch - dimensions of the box

Hi,
electricians are putting the wiring in my new house and they will start installing the boxes tomorrow.
At the last minute, the plan for switches was changed so as to mount Xiao Mi Aquara (as in the photo). From what I can see, it requires square cans, and for us the standard is round.
Anyone know what size can to order so that the switch fits? I have not found such info anywhere, because the can is usually simply added to the switch ... I ordered 1 item quickly, but it will not come until the day after tomorrow, and I have to confirm the cans today, so I will be grateful for your quick help.

Buddy, order in the EU standard

Thanks for the dimensions. As for the photo from the "EU standard panel", was it not meant to illustrate the differences? Because nowhere have I found Aqara with a European back.
Do you have any bearing on such a switch?

Maybe it really is as you write. I made a suggestion in the Chinese auction, but it is in vain to look for the EU version in the selection.

I found information that the box attached to the switch is 88 mm. The photo shows that the spacing between the holes for mounting screws is 60 mm. So the topic seems to be closed.
