Stub Analytics Plugin builds successfully but is not detected by Nx Witness

Hello Nx Team,

I am developing an analytics plugin using the Nx Witness SDK.

Environment:
- Nx Witness Version: 6.0.6.41837
- SDK Version: 6.0.6.41837
- OS: Ubuntu Linux

Problem:
The stub analytics plugin builds successfully and generates:
libstub_analytics_plugin.so

However, Nx Witness does not detect or show the plugin in the Desktop Client.

What I have done:
1. Built the plugin using CMake successfully.
2. Copied the generated .so file into the Nx Witness plugins directory.
3. Restarted the mediaserver service.
4. Checked mediaserver logs.

Expected:
The analytics plugin should appear in Nx Witness.

Actual:
The plugin is not visible.

Logs:
sudo journalctl -u networkoptix-mediaserver.service -f

I would like to know if any additional files are required, such as:

Thank you.
