Integration with Orthanc Worklist Plugin

In our small new ultrasound clinic, sonographers manually enter patient demographics into the ultrasound machine and we are wondering if we could integrate Orthanc Worklist plugin functionality to our Orthanc version 1.12.6 on macOS so that the ultrasound machine can send a C-FIND query to Orthanc and get the worklist? I assume we need to add libOrthancWorklist.so to Orthanc files but after searching the Orthanc book, I could not find the link to download the plugin. Would you please advise where we can find the download link to libOrthancWorklist.so?
