React: how to show progress of Axios during get request (not download or upload)

Question

I want is to show a progressbar while Axios is getting my requests. axios package has both onDownloadProgress and onUploadProgress to show a progressbar during download or upload, but no progress bar during get request. I've searched a lot of questions and articles but they are always about download/upload progress or for Vue.js and I fail to understand how to do it in React.

I have the following code down below (which will not work because I'm not downloading).

Ideally, I'd write it myself; but I'm willing to consider using axios-progress package if someone could explain me how I'd integrate the loadProgressBar() with my Axios request.

request = () => {
    this.setState({error: null, results: []})
    axios({
        method: 'get',
        url: process.env.REACT_APP_API_LOCALS,
        responseType: 'json',
        onDownloadProgress: (progressEvent) => {
            var percentCompleted = Math.round((progressEvent.loaded * 100) / progressEvent.total);
            this.setState({
                loading: percentCompleted
            })
        },
    })
    .then(
        (response) => {
            console.log(response)
            this.setState({
                results: response.data.results,
                error: null,
                totalPages: Math.ceil(response.data.count / response.data.results.length)
            })  
        }
    )
    .catch(
        (error) => {
            this.setState({
                loading: null,
                error: true
            })  
        }
    );
}

Here's what worked for me in React:

const client = axios.create({
  baseURL: 'http://localhost:10000/v1/client',
  timeout: 20000
})

let result = await client.get('/fetchMeSomething', {
  onDownloadProgress: progressEvent => {
    const total = parseFloat(progressEvent.currentTarget.responseHeaders['Content-Length'])
    const current = progressEvent.currentTarget.response.length

    let percentCompleted = Math.floor(current / total * 100)
    console.log('completed: ', percentCompleted)
  }
})
.then(res => {
  console.log("All DONE: ", res.headers)
  return res.data
})
