How to use the presidio-analyzer.analyzer.analyzer_engine.AnalyzerEngine.__convert_results_to_proto function in presidio-analyzer

def Apply(self, request, context):
        logging.info("Starting Apply")
        entities = AnalyzerEngine.__convert_fields_to_entities(
            request.analyzeTemplate.fields)
        language = AnalyzerEngine.get_language_from_request(request)
        results = self.analyze(request.text, entities, language,
                               request.analyzeTemplate.allFields)

        # Create Analyze Response Object
        response = analyze_pb2.AnalyzeResponse()

        # pylint: disable=no-member
        response.analyzeResults.extend(
            AnalyzerEngine.__convert_results_to_proto(results))
        logging.info("Found %d results", len(results))
        return response
