Broken reset button on Aqara motion sensor

The small reset button on the Aqara RTCGQ11LM Motion Sensor seems to have been broken. I suspect I’ve pushed too hard with a pen and now I can’t set it in pairing mode for SmartThings to discover it. Is there any way to work around this? By opening the case?

Opening the case is relatively easy with a small screwdriver. (did this for all my 5 devices)
but it’s 15$ don’t spend a lot of effort on it
