You first need to make classes the same as their entities, then you need to use JsonUtility convert a json string to the classes you created. I made an example here using a json file in the resources folder to make it clear how you need to read this data, something like this:

using UnityEngine;
using System;
using System.IO;
using System.Text;
using System.Globalization;

public class ReadJson : MonoBehaviour
{
    public ContainJson classeFromJson;
    // Start is called before the first frame update
    void Start()
    {
        ReadJsonFromResources();
    }

    public void ReadJsonFromResources()
    {
        string json = "";

        using (StreamReader r = new StreamReader("./Assets/Resources/PlaceHolderJSON/data.json", Encoding.GetEncoding(CultureInfo.GetCultureInfo("pt-BR").TextInfo.ANSICodePage)))
        {
            json = r.ReadToEnd();
        }

        ContainJson containJson = JsonUtility.FromJson<ContainJson>(json);

        classeFromJson = containJson;
    }
}

[Serializable]
public class ContainJson
{
    public Data data;
    public int ID;
    public Caps caps;
    public string cap_key;
    public string[] roles;
    public AllCaps allcaps;
    public string filter;

}


[Serializable]
public class Data
{
    public string ID;
    public string user_login;
    public string user_pass;
    public string user_nicename;
    public string user_email;
    public string user_url;
    public string user_registered;
    public string user_activation_key;
    public string user_status;
    public string display_name;

}

[Serializable]
public class Caps
{
    public bool administrator;
}


[Serializable]
public class AllCaps
{
    public bool switch_themes;
    public bool edit_themes;
    public bool edit_others_user_registrations;
    public bool publish_user_registrations;
    public bool read_private_user_registrations;
    public bool delete_user_registrations;
    public bool delete_private_user_registrations;
    public bool delete_published_user_registrations;
    public bool delete_others_user_registrations;
    public bool edit_private_user_registrations;
    public bool edit_published_user_registrations;
    public bool manage_user_registration_terms;
    public bool edit_user_registration_terms;
    public bool delete_user_registration_terms;
    public bool assign_user_registration_terms;
    public bool manage_email_logs;
    public bool administrator;

}
