De parameter `name` is gedefinieerd als `Optional[str]`, maar is **niet optioneel**, je kunt de functie niet aanroepen zonder de parameter:

```Python
say_hi()  # Oh, nee, dit geeft een foutmelding! 😱
```

De `name` parameter is **nog steeds vereist** (niet *optioneel*) omdat het geen standaardwaarde heeft. Toch accepteert `name` `None` als waarde:

```Python

	pod, ns := buildFakePodAndNSForClient()

	proxy := corev1.Container{Name: "istio-proxy"}
	app := corev1.Container{Name: "app"}

	pod.Spec.Containers = []corev1.Container{app, proxy}
	pod.ObjectMeta.Annotations = map[string]string{annotation.SidecarStatus.Name: "true"}
	ns.ObjectMeta.Labels = map[string]string{label.IoIstioDataplaneMode.Name: constants.DataplaneModeAmbient}

	testDoAddRun(t, cniConf, testNSName, pod, ns)
