Unable to get instance details through mongodb receiver

Describe the issue you're reporting

I have a central collector running on k8 cluster. I have configured mongodb receiver in collector and the collector exports the metrics to googlemanaged prometheus. I am able to see mongodb metrics like mongo_cache_operations and mongo_collection_count but the metrics do not have any labels about which instance is reporting these metrics. Below is my collector configuration. Can you let me know how I can fetch mongodb instance details in metric labels.

Collector version: 0.97.0
