How to use the mobx-utils.chunkProcessor function in mobx-utils

constructor(appStore, subscriptionManager, queryManager) {
        this.appStore = appStore;
        this._itemsMap = observable.map({});
        this.subscriptionManager = subscriptionManager;
        this.queryManager = queryManager;

        this.subscriptionManager.subscribeToAllSessions(
            this.handleSubscription
        );

        let bufferSize = this.bufferSize;
        const stop = chunkProcessor(this.logsBuffer, chunk => {
            let itemsCount = this.logs.length + chunk.length;
            let offset = itemsCount > bufferSize ? itemsCount - bufferSize : 0;
            this.logs.replace(
                this.logs.slice(offset).concat(chunk)
            )
            this.logsBuffer.clear();
        }, 200, bufferSize)
    }
