Plugins tab not found on System Administration screen

Hi,

I have installed tree trail version NX witness bundle on Windows PC. When I am navigating to System Administration, don't plugins tab over there. Is it due to the trail version I installed?
 I don't find plugins tab in Camera settings as well. I searched about this in the community and could not find much info. I want to try running analytics plugins. Can someone help me with the way to enable it.

Thanks,
Pandu.
