Refresh PDS/VDS once file changes or new file added to s3

I have uploaded few files to AWS s3 bucket and i am able to create PDS/VDS successfully in Dremio Cloud by calling Dremio’s REAT API.

My s3 bucket files changes manually by users.

  1. Users can add new files to the same bucket
  2. Also, they can modify existing file and upload to the same bucket.

Now, I am facing issue to update the existing PDS and VDS. Not Sure how can i achieve this via API.
