How to use the google-ads-node.DismissRecommendationRequest.DismissRecommendationOperation function in google-ads-node

const operations = resourceName.map(name => {
                const operation = new DismissRecommendationRequest.DismissRecommendationOperation()
                operation.setResourceName(name)
                return operation
            })
            request.setOperationsList(operations)

public async dismissRecommendation(
        resourceName: string | string[],
        options?: ServiceCreateOptions
    ): Promise {
        const request = new DismissRecommendationRequest()
        request.setCustomerId(this.cid)

        if (resourceName instanceof Array) {
            const operations = resourceName.map(name => {
                const operation = new DismissRecommendationRequest.DismissRecommendationOperation()
                operation.setResourceName(name)
                return operation
            })
            request.setOperationsList(operations)
        } else {
            const operation = new DismissRecommendationRequest.DismissRecommendationOperation()
            operation.setResourceName(resourceName)
            request.setOperationsList([operation])
        }

        if (options && options.hasOwnProperty('partial_failure')) {
            if (!request.setPartialFailure) {
                throw new Error(`This method does not support the partial_failure option.`)
            }
            request.setPartialFailure(options.partial_failure as boolean)
        }

        const response: DismissRecommendationResponse.AsObject = await this.service.dismissRecommendation(request)
        return {
            request: request.toObject(),
            partial_failure_error: response.partialFailureError,
            results: response.resultsList.map(r => r.resourceName),
