Reproduction of the bug/regression with instructions

How to reproduce

Pull this repo: https://github.com/erikwski/POC-MFE-ABSTRACTION.git

• Install the dependency at least on the folder cdo, clm-shared, shell
• Run the npm run build inside the clm-shared
• Use npm link for link clm-shared with cdo and shell
• Start locally the cdo and the shell
• Open the shell at localhost:4200 and click the button navigate to CDO
• Injection Error

Explanation:

I need to implement an abstraction class in two different shell, the abstraction will be in a shared folder and the implementation must stay in the shell folder.
How can i declare to my remote that it will receive the abstract from the shell? Now the error that it's throwing is:

ERROR NullInjectorError: R3InjectorError(Environment Injector)[DataService2 -> DataService2]: 
  NullInjectorError: No provider for DataService2!

I want to reproduce something that i already make using monorepo like this: https://github.com/erikwski/clm-monorepo/tree/master/libs/shared/notification/feature-emit/src/lib

Expected behavior

I need to understandand how to declare dependency injection of the remote to take some services from the parent.
