Now that you have developed the prints, you can make copies of them with fingerprint lifting tape. The CA fumes bond to the surfaces of the items and latent print visualization is, hopefully, achieved. But if the cabinet has an automated limited time purge cycle, the CA still atop a warm heat source will continue to fume throughout and well past when that purge has completed its cycle.
