+     *     failCommands: ['insert']
+     *   }
+     * });
+     * ```
+     * Via the command monitoring CommandSucceededEvent, configure a fail point with error code 10107 (NotWritablePrimary) and a NoWritesPerformed label:
+     *
+     * ```js
+     * db.adminCommand({

+     *     failCommands: ['insert']
+     *   }
+     * });
+     * ```
+     * Drivers SHOULD only configure the 10107 fail point command if the the succeeded event is for the 91 error configured in step 2.
+     *
+     * Attempt an insertOne operation on any record for any database and collection. For the resulting error, assert that the associated error code is 91.
