Isaac Sim Custom sensors

Hi,

Currently, I’m trying to implement custom sensors (thermal camera and controllable led lamp) for robot inside Isaac Sim using extensions. Maybe there are some open-source examples of it (for example lidar or generic camera). As all examples available on GitHub and inside Isaac sim release are pre-compiled into .so files, thus cannot be used as examples. Moreover, there is an issue with documentation about USD schemas (USD Schema — Omniverse Kit 102.1.2+release.46667.2027b54e.teamcity documentation) - confluence links seem broken/not available, maybe somehow we can get access to them?
