Unity DOTS unable to see Roslyn source generators code from Unity ECS systems like use of SystemAPI

I no longer see any generated code for Unity DOTS ecs systems. Is this a setting I may have disabled? How can I enable this code vision such that I can browse the source gen?

“To inspect your systems, use an IDE that supports source generation, such as Visual Studio 2022+ or Rider 2021.3.3+. You can then select Go To Definition to inspect the generated code on the system you're using SystemAPI within. This illustrates why you need to mark systems as partial.”
