How to parse Escaped JSON Array in Net Core

I have this JSON that I get from API, I have trouble with Parsing the JSON to get the value I want this is the JSON

["{\"UPDATE_TYPE\":\"NOTE_ADDED\",\"UPDATE_TEXT\":\"Notenya begini\",\"UPDATE_TIME\":\"Fri, Dec 4, 17:02\",\"UPDATE_TIME_EPOCH\":1607076127834,\"ATTACHMENT\":\"\"}","{\"UPDATE_TYPE\":\"STATUS_UPDATED\",\"UPDATE_TEXT\":\"Complete\",\"UPDATE_TIME\":\"Fri, Dec 4, 17:02\",\"UPDATE_TIME_EPOCH\":1607076127840,\"ATTACHMENT\":\"\"}"]

I already tried to Deserialize it twice to remove the encoding. And I try to use Regex too but I still get an error when tried to parse using Newtonsoft JAray.Parse. I never encounter JSON like this before.
any suggestion to remove the encoding and parse the value from that JSON?

Method 1

1. Remove double quotes between [ and {, same at the end of the string.
2. Remove the in json string.

This is the specific step, intercepted part of the json string.

        var str = "["{\"UPDATE_TYPE\":\"NOTE_ADDED\",\"UPDATE_TEXT\":\"Notenya begini\",\"UPDATE_TIME\":\"Fri, Dec 4, 17:02\"}"]";

        Regex rg = new Regex("(?<=(" + "{" + "))[.\s\S]*?(?=(" + "}" + "))", RegexOptions.Multiline | RegexOptions.Singleline);
        var lstr= rg.Match(str).Value;
        
        var jstr = "[{" + lstr + "}]";
        var model=jstr.Replace(@"", "");
        var result=JsonConvert.DeserializeObject<List<Model>>(model);

Model.

public class Model
{
    public string UPDATE_TYPE { get; set; }
    public string UPDATE_TEXT { get; set; }
    public string UPDATE_TIME { get; set; }
}
