            List<Object> candidates = (List<Object>)parsedResponse.get('candidates');
            
            // Assuming there's at least one candidate and you want the first one
            Map<String, Object> firstCandidate = (Map<String, Object>)candidates[0];
            
            // Navigate to "content" -> "parts"
            Map<String, Object> content = (Map<String, Object>)firstCandidate.get('content');
            List<Object> parts = (List<Object>)content.get('parts');
            
            // Assuming there's at least one part and you want the text from the first part
