Backup the CSLFE link the collection with the encrption keyvault document

Working with Data Drivers

Hi, I am using CSLFE and I want to take a backup of my employee collection with let’s say {orgId: ObjectId(‘xxx’)}

but the collection has encrypted fields, and I found CSLFE nodejs driver is created encryption.__keyValut collection as well and I have to back up that collection as well.

but the issue is I don’t know how to map and link the employee collection to the correspondence and proper document(record) on the encryption, keyValut collection to backup that record as well.

Please advise
