Great explained.

Just do add little more to my query.

Suppose i have 2 services in a feature module.

I need service 1 to be hidden or you can say not exposed to parent or root module that import it.

Service 1 will only be used by service 2 .

Service 2 will only be exposed by the feature module to whomsoever imports the module and use our service 2 only.

Either we import our module in root module or some other feature module we are only exposing our service 2.

Does such scenario can be implemented?
Please let me know if i am missing or not able to understand

Regards
