How to use the abortcontroller-polyfill/dist/cjs-ponyfill.abortableFetch function in abortcontroller-polyfill

function (url, opts) {
        performance.mark(url + " - begin")
        const { fetch } = abortableFetch(nodeFetch) as any
        return fetch(url, opts).then(_ => {
            performance.mark(url + " - end")
            const measure = () => performance.measure(_.url, url + " - begin", url + " - end")
            performance.clearMarks(url + " - begin")
            if(timeout)
                setTimeout(measure, timeout)
            else
                measure()
            return _
        })
    }
