How in Symfony 5.2 to bind an Entity with a custom unique parameter passed in the controller?

Question

symfony

there is a url field, you need to get the Entity by this field (not by id).
That is, the selection must be performed by the Proposition url

/**
     * @Route("/present/{url}", name="cv_present", methods={"GET","POST"}, requirements={"url"="[a-z0-9-]+"})
     * @param Proposition $proposition
     * @param Request $request
     * @param CVService $CVService
     * @return Response
     */
    public function present(Proposition $proposition, Request $request, CVService $CVService): Response
    {
