Error Trying to Covert List<string> In Xamarin Forms

I am using an asp.net api to query from my xamarin app to SQL Server. Below is how I am querying the API, and setting up the return type, but I am getting an error of

Can not convert List to List

What do I need to change in my code so that this will execute as desired?

public List<string> GetApprovalGrid()
{
    string URI = "XXXXXXX/api/Xamarin/properties";

    using (var webClient = new System.Net.WebClient())
    {
        var json = webClient.DownloadString(URI);

        var message = JsonConvert.DeserializeObject<List<string>>(json);
        return message;
     }
}

public class ApproveUsers
{
    public int ID { get; set; }
    public string fname { get; set; }
    public string lname { get; set; }
    public string phone { get; set; }
    public string company { get; set; }
    public string approveduser { get; set; }
}

private void LoadApproveUserGrid()
{
    List<ApproveUsers> ApprovedUser = new List<ApproveUsers>();
    //this line throws the error
    ApprovedUser = dal.GetApprovalGrid();
    //more code here
}

ApprovedUser is of type List<ApproveUsers> but GetApprovalGrid() returns List<string>

EDIT:

JsonConvert.DeserializeObject<List<ApproveUsers>>(json);

if your json is correctly formatted

EDIT2: you need to change the method signature to this too:

public List<ApproveUsers> GetApprovalGrid()
