Where to describe controllers in laravel modular structure?

Question

PHP

The Laravel backend API project uses a modular approach - https://nwidart.com/laravel-modules/v6/introduction.
Also, in each of the modules, the Service - Repository pattern is applied.

Question: where is the best place to describe controllers, and where to describe routes? On the top layer or in the modules themselves?
Please tell me your opinion.

Thanks in advance for your replies!
