Where to install a plex bundle?

[sim667]

I want to install the audnexus bundle into plex (installed via TOS 5.1 App Store)

But can't workout where the plex installation is to actually put it into the plug in library, I've tried both the MOD_CONFIG folder, and where there seem to be lots of bundles in /usr/local/plex/plexmediaserver/Resources/Plug-ins-836b34c27, but on reloading plex I still can't use audnexus as an agent. Can you advice me where tos has installed plex to?
