• The override decorator is imported but not used in the file. Remove the unused import statement.

from typing import override  # pragma: no cover

python/semantic_kernel/connectors/memory/mongodb_atlas/mongodb_atlas_collection.py:169

• [nitpick] The log message could be more descriptive. Consider changing it to 'Upserted records: %s' % result.

logger.debug("Upserted records:", result)

python/semantic_kernel/connectors/memory/mongodb_atlas/mongodb_atlas_collection.py:170

• Add a check for 'result.upserted_ids' before iterating over it to avoid potential errors.

return [str(value) for key, value in result.upserted_ids.items()]

• [nitpick] The logic for setting 'managed_client' in the constructor is inconsistent with the logic used in 'AzureCosmosDBforMongoDBCollection'. Consider updating for consistency.

managed_client = kwargs.get("managed_client", not mongo_client)

Will there be unit and integration tests for the new connector in a separate PR?
