How to check whether one node in API response has same value under all object using postman tests?

Suppose a API request fetches a users id, email address and their designated role. Sample API Request below:

GET: /v1/users HTTP/1.1
Content-Type: application/json
Authorization: bearer {access_token}

For the above request, the following is the response:

{
    "content": [
        {
            "id": 1,
            "email": "random@random.com",
            "full_name": "AlbusDumbledore",
            "role": "OWNER"
        },
        {
            "id": 40,
            "email": "random1@random1.com",
            "role": "OWNER"
        }
],
    "last": false,
    "total_elements": 2,
    "total_pages": 1,
    "sort": null,
    "first": true,
    "number_of_elements": 2,
    "size": 20,
    "number": 0
}

Now, what will be the test in postman to make sure that all the returned values under role node is equal to OWNER?
