Then you need to find where the plist files are (i.e. com.bluejeans.app.detector.plist).
You can disable an entry from launchctl list:
launchctl disable uid/<your user uid>/com.bluejeans.app.detector
You can also unload if you find the actual file
launchctl unload ~/Library/LaunchAgents/com.bluejeans.app.detector.plist
There were a couple differently named bluejeans agents.
