Module class not found for Referer Security (ModuleAccessControl) on 4.9.5+3 Trial License

Since the server cannot find these core module classes, my main question is:

Are the security modules like ModuleAccessControl intentionally excluded from the Trial License for Wowza Streaming Engine 4.9.5+3?

If they are not supposed to be excluded, what could be causing the Module class not found error on a fresh installation? I also noted that the legacy wms-plugin-collection.jar is not available for download anywhere.

Thank you for any help or insights you can provide.

I believe this module was once on the Wowza website as a downloadable jar, including source code, and was later provided on the Wowza public github. My memory is that it was released under the Wowza Public License.

No idea what the current status is, hopefully someone from Wowza can confirm if I am incorrect and status
