Why is the Json deserializer not working?

I'm quite new to Json files and Blazor, and I was trying to deserialize a Json string, but when I try to fill a list with objects obtained via deserializer the list is full of null objects. I'm also using Flurl, I don't know if it's of any relevance, but I'll just mention it to be sure.

The string I'm deserializing is this one :

[
    {
        "id": 1,
        "description": "DASHBOARD",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 6,
        "description": "Accounting",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 7,
        "description": "Anti-avoidance obligations",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 8,
        "description": "Personal data",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 9,
        "description": "Date",

    },
    {
        "id": 12,
        "description": "F24 - F23 and communications",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 13,
        "description": "Management",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 14,
        "description": "StudyOK",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 15,
        "description": "730",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 16,
        "description": "770",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 17,
        "description": "Fees",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 18,
        "description": "Certification",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 19,
        "description": "IMU",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 20,
        "description": "ISA",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 21,
        "description": "IVA",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 22,
        "description": "PF",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 23,
        "description": "SC",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 24,
        "description": "SP",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    },
    {
        "id": 25,
        "description": "Widget",
        "position": 0,
        "enabled": true,
        "itemSections": [],
        "users": []
    }
]

This is the code :

var tokenTrimmed = token2.Split("\"token\":\"")[1].Split('"')[0].Trim();
result = await url.WithOAuthBearerToken(tokenTrimmed).GetStringAsync();

var jsonDocument = JsonDocument.Parse(result);


Console.WriteLine(jsonDocument.RootElement.ToString());

items = JsonSerializer.Deserialize<List<GridList>>(jsonDocument.RootElement);

This is the GridList Class :

@code {
    public int Id { get; set; }
    public string Description { get; set; }
    public int Position { get; set; }
    public bool Enabled { get; set; }
    public List<string> ItemSections { get; set; }
    public List<string> Users { get; set; }
}

And this is what I get:

So to summarize:

var options = new JsonSerializerOptions
{
    PropertyNameCaseInsensitive = true,
});

var result = JsonSerializer.Deserialize<List<GridList>>(yourJsonAsString, options);
