How to use the graphene-django.graphene_django.debug.sql.types.DjangoDebugSQL function in graphene-django

if vendor == 'postgresql':
                # If an erroneous query was ran on the connection, it might
                # be in a state where checking isolation_level raises an
                # exception.
                try:
                    iso_level = conn.isolation_level
                except conn.InternalError:
                    iso_level = 'unknown'
                params.update({
                    'trans_id': self.logger.get_transaction_id(alias),
                    'trans_status': conn.get_transaction_status(),
                    'iso_level': iso_level,
                    'encoding': conn.encoding,
                })

            _sql = DjangoDebugSQL(**params)
            # We keep `sql` to maintain backwards compatibility
            self.logger.object.sql.append(_sql)
