      Depending on how "large" the large document is, one gets 3 different exceptions. All of the following are > maxBsonSize:

      ```

      large = {"large": "1" * 1024 * 1024 * 16} # About maxBsonObjectSize. larger than the document size limit but under the command size limit
      xlarge = {"xlarge": "1" * 1024 * 1024 * 18} # Over maxBsonObjectSize. document larger than the command size limit:
      xxl = {"xxl": "1" * 1024 * 1024 * 48} # Over max_message_size: 48_000_000 <== Only this one throws DocumentTooLarge

      The errors for the are the following
