codeigniter 4 "need define" in the model this data output->set_header

This would also be valid for calls from controllers or bookries, I simply consult because due to the great diversity there are many forms of calls, but the most appropriate ones would be great.

Example wants to set this from a helper, a library.

PHP Code:

//If you still want to do this in the model
Service::response()->setHeader('Pragma', 'no-cache'); 


I clarify this code is the one that works apparently in BaseController:

PHP Code:

$this->response = \Config\Services::response()->setHeader('Pragma', 'no-cache'); 


In any class of your application, you can interact with the Response class by getting an instance of it using \Config\Services::response()
But in a controller, an instance of the Response class can also be accessed through the $this->response property. Because this property gets an instance of the Response class when the controller is initialized.
