           string? TryGetDeciphererFuncBody()
            {
                var funcName = Regex.Match(_root, @"(\w+)=function\(\w+\){(\w+)=\2\.split\(\x22{2}\);.*?return\s+\2\.join\(\x22{2}\)}")
                    .Groups[0]
                    .Value;

                return funcName;

                var escapedFuncName = Regex.Escape(funcName);

                return Regex.Match(_root, $@"(?!h\.){escapedFuncName}=function\(\w+\)\{{(.*?)\}}", RegexOptions.Singleline)
                    .Groups[1]
                    .Value
                    .NullIfWhiteSpace();
            }
