string i want to convert:
vless://Parsashonam-8@[2a01:4f9:c011:1622::1]:12535?type=tcp&security=none#❔XX | ???? | vless | @Parsashonam | 5

string vlessUrl = "vless://Parsashonam-8@[2a01:4f9:c011:1622::1]:12535?type=tcp&security=none#❔XX | ???? | vless | @Parsashonam | 5";

// Remove the "vless://" prefix
string base64String = vlessUrl.Replace("vless://", "");

// Decode from Base64
byte[] bytes = Convert.FromBase64String(base64String);
string jsonString = Encoding.UTF8.GetString(bytes);

// Parse JSON
JObject configJson = JObject.Parse(jsonString);

Console.WriteLine(configJson);
