How to use the google-ads-node.UploadCallConversionsRequest function in google-ads-node

public async uploadCallConversions(conversions: Array): Promise {
        const protobufs = this.buildResources('CallConversion', conversions) as Array

        const request = new grpc.UploadCallConversionsRequest()
        request.setCustomerId(this.cid)
        request.setConversionsList(protobufs)
        request.setPartialFailure(true)
