How to separate air 2s lens module from CCD board?

I've got an air 2s camera whose autofocus motor is not functioning properly. Everything else about the camera (and of the gimbal) works fine - calibration is good, everything. Just that the autofocus motor click-click-clicks upon startup and it is most of the time is unable to focus on anything.

I have sourced a new lens component (the thing with the optics and the autofocus motor and related electronics). The thing is, I cannot figure out how to separate the CCD board (which contains the sensor) from the old/bad lens component. I've tried prying in different ways but I really don't want to break the CCD board. I was wondering if anyone on the forum knows how these two parts are attached and how I can separate them. It may be that we're just talking about some glue that I need to heat up to separate, but I'd like to consult with those in the know before giving it a go.

Can anyone who has experience describe how the CCD board on the back of the camera module attaches and can be separated from the lens and lens housing?
