How to use the @casual-simulation/aux-vm.filterAtomFactory function in @casual-simulation/aux-vm

constructor(
        user: AuxUser,
        config: AuxConfig,
        options: RemoteAuxChannelOptions
    ) {
        super(user, config, options);
        this._partitionOptions = {
            ...(options.partitionOptions || {
                defaultHost: null,
            }),
            treeOptions: {
                filter: filterAtomFactory(() => this.helper),
            },
        };
        //  {
        //     defaultHost: defaultHost,
        //     store: options.store,
        //     crypto: options.crypto,
        //     treeOptions: {
        //         filter: filterAtomFactory(() => this.helper),
        //     },
        // };
    }
