       The bson_iter_document() function shall retrieve the raw buffer of a sub-document from iter. iterMUST be
       on  an  element  that  is  of  type BSON_TYPE_DOCUMENT. This can be verified with bson_iter_type() or the
       BSON_ITER_HOLDS_DOCUMENT() macro.

       • iter: A bson_iter_t.

       • document_len: A location for the length of the document in bytes.

       • document: A location for the document buffer.
