Application add query services

[levinhne]

Hi!
I really like this project of yours. I have the following problem, please help.
In internal/trainings/app/command I see there is a services.go, similarly in internal/trainings/app/query I also want a services.go, but when I do so Go gives an error in https: //github.com/ThreeDotsLabs/wild-workouts-go-ddd-example/blob/master/internal/trainings/service/service.go#L39 because this function is passing command.TrainerService, command.UserService.
Please help me to know more.
Thank you!
