  48       * Supported options:
  49       *
  50       *  * arrayFilters (document array): A set of filters specifying to which
  51       *    array elements an update should apply.
  52       *
  53       *  * bypassDocumentValidation (boolean): If true, allows the write to
  54       *    circumvent document level validation.
  55       *
  56       *    For servers < 3.2, this option is ignored as document level validation
  57       *    is not available.
  58       *
  59       *  * collation (document): Collation specification.
  60       *
  61       *    This is not supported for server versions < 3.4 and will result in an
  62       *    exception at execution time if used.
  63       *
  64       *  * hint (string|document): The index to use. Specify either the index
  65       *    name as a string or the index key pattern as a document. If specified,
  66       *    then the query system will only consider plans using the hinted index.
  67       *
  68       *    This is not supported for server versions < 4.4 and will result in an
  69       *    exception at execution time if used.
  70       *
  71       *  * maxTimeMS (integer): The maximum amount of time to allow the query to
  72       *    run.
  73       *
  74       *  * projection (document): Limits the fields to return for the matching
  75       *    document.
  76       *
  77       *  * returnDocument (enum): Whether to return the document before or after
  78       *    the update is applied. Must be either
  79       *    FindOneAndUpdate::RETURN_DOCUMENT_BEFORE or
  80       *    FindOneAndUpdate::RETURN_DOCUMENT_AFTER. The default is
  81       *    FindOneAndUpdate::RETURN_DOCUMENT_BEFORE.
  82       *
  83       *  * session (MongoDB\Driver\Session): Client session.
  84       *
  85       *    Sessions are not supported for server versions < 3.6.
  86       *
  87       *  * sort (document): Determines which document the operation modifies if
  88       *    the query selects multiple documents.
  89       *
  90       *  * typeMap (array): Type map for BSON deserialization.
  91       *
  92       *  * upsert (boolean): When true, a new document is created if no document
  93       *    matches the query. The default is false.
  94       *
  95       *  * writeConcern (MongoDB\Driver\WriteConcern): Write concern.
  96       *
  97       *    This is not supported for server versions < 3.2 and will result in an
  98       *    exception at execution time if used.
