How to view docstrings for functions in my submodules?

My local package is organized in modules, which my top-level package file includes and then uses. When working on the code in a REPL (after “using Revise, MyPackage”), I can see my documentation for the few toplevel functions that MyPackage exports, but I can’t see the documentation for the many functions defined in the sub-modules.

Is there any way for a developer to make their docstrings accessible without having to export all of the documented function names from the toplevel module?

Thanks. (Julia 1.8.4)

Thanks for the very prompt and helpful response!
