    :dbcommand:`cleanupOrphaned` command to clean up orphaned documents.
    Instead, use this command to wait for orphaned documents in a chunk

    :bsontype:`MaxKey` for a specified namespace to be
    cleaned up from a majority of a shard's members.

    In MongoDB 4.2 and earlier, :dbcommand:`cleanupOrphaned` initiated 
    the cleanup process for orphaned documents in a specified namespace 
    and shard key range.
