Copy Encrypted data from one MongoDB cluster to another cluster unencrypted

Hi there,

I have a MongoDB Atlas cluster that has CSFLE(Client Side field level encrypted) data.

I need to create an unencrypted backup of this database.

The first idea that came to mind is to spin up another Mongo database without without any CSFLE, and then write a script that basically query every document in the encrypted database, and then insert each one in the unencrypted database then once finished I can take a backup of the new database.

Is there any simpler way to go around this, or any command line tool that can let me achieve this better without having to implement all the above just to get an unencrypted backup?

Thanks in advance.
