Change battery on Aqara OPPLE

Hi mates, I’ve just received these devices, they are pretty new and I can’t find disassembly infos around, they seems “one piece” and the only way possible to change the battery can be open the front buttons covers. But spoil them seems very easy… and I don’t want to try just for check. Also, there may be issues with covers if removed unaccurately.
Has someone figured out how?

Thank you
