Unity Modules Setup

To build Unity dedicated servers for PlayFlow, you need to install specific Linux build modules. PlayFlow deploys servers on Linux infrastructure, so these modules are essential for creating compatible server builds.
Without the proper Linux modules installed, Unity will not be able to build dedicated servers for PlayFlow deployment.
