Android Studio 4.1 should have dagger navigation support where inject, provides, or bindings are defined. It's nowhere near perfect but might be useful for new comers.
Also, if they are already familiar with Dagger, they shouldn't have hard time finding related dependencies in a codebase. I find it useful to have a graph of high level bindings between components and modules that summarizes the general architecture of your Dagger setup. Details should be discovered by individuals by simply navigating the code 🤷
