deprecated Creation of dynamic property

Hello,
I'm using php 8.2 and ci 4.3.2 and i got
Creation of dynamic property App\Controllers\Document::$compteModel is deprecated

APPPATH/Controllers/Document.php at line 17

PHP Code:

11    public function initController(
12        \CodeIgniter\HTTP\RequestInterface $request,
13        \CodeIgniter\HTTP\ResponseInterface $response,
14        \Psr\Log\LoggerInterface $logger
15    ) {
16        parent::initController($request, $response, $logger);        
17        $this->compteModel = new compteModel();
18        $this->ecritureModel = new ecritureModel();
19    } 


As you can see it above, in all my controllers, i put access to models in the init part to avoid writing many times

PHP Code:

[...] new someModel() 


in the different methods

I fought that, adding

Code:

protected $compteModel;

solved the issue

Is that a good way ?

Thanks, nice day !
