How to add Person to ContactType?

Question

I have an array of multiple contactTypes with the same telephone number, like this:

"contactPoint": {
    "@type": "ContactPoint",
    "areaServed": "DE",
    "contactType": [
        "Kundenservice",
        "Anfragen"
    ],
    "telephone": "+1111111"
}

Now I want to add a person to each contactType. Trying do it on this way:

"contactPoint": {
    "@type": "ContactPoint",
    "areaServed": "DE",
    "contactType": [
        "Kundenservice": {"@type": "Person", "name": "John Q"},
        "Anfragen"
    ],
    "telephone": "+1111111"
}

I get no validation. What is the right way to do this?
