Progress bar/progress description using Node.js and Puppeteer

Question

I've some code that uses Puppeteer that I am using to grab random words from a website that generates them. The process simulates a drop-down click, entry, and mouse click and then grabs text generated on the next page and saves it into a .json file in the cwd.

I am trying to figure out the best way to display some form of a progress descriptor of the happenings like a percentage (as I would like to have the Puppeteer code run in headless mode) but I cannot figure how I might get that to work under my current set up. Does anyone have any suggestions? Also, this is my first quarter in JS so I understand I may have done things in ways that are not polished, please be kind.

// instantiate puppeteer 
const puppeteer = require('puppeteer');



// function call for puppeteer
async function launchSearch(){
    // website that generates random words where the words will come from
    const url = 'https://www.sodacoffee.com/words/list-generator';
    // button div id to click and generate more word searches
    const buttonClick = '#ctl00_ContentPane_btn';
    // div id for the drop-down selector on the url asking how many results we want
    const numResultsPerClick = '#ctl00_ContentPane_resultscounter';
    // puppeteer browser launch options
    const browser = await puppeteer.launch({
        // headless == no graphical representation of the browser
        headless: false,
    });
    // create new browser element named page
    const page = await browser.newPage();
    // go to word generator URL
    await page.goto(url);
    // variable searches DOM for div id (declared above)
    const numWordsScrape = await page.$(numResultsPerClick);
    // select the element
    await numWordsScrape.click()
    // type 50 to return 50 random words
    await numWordsScrape.type('50');
    // to prevent some errors due to promises, Promise.all() seemed to be best to get results
    await Promise.all([
        // wait until the page has loaded (url)
        page.waitForNavigation(),
        // click button
        page.click(buttonClick)
    ])
    // site *should* have advanced forward to the next page with 50 results 
    const textAfterButtonClick = await page.evaluate(
        // create an array from the results of the query to the DOM, and map those specific elements <tr> -> to their inner text values
        () => Array.from(document.querySelectorAll('#ctl00_ContentPane_GridView1 tbody tr')
        ).map((elem) => elem.innerText.trim())
    );

    // instantiate file handling 
    const fs = require('fs');
    const file = 'word.txt';
    fs.writeFileSync('./words.json', JSON.stringify(textAfterButtonClick), err => err ?
    console.log(err): null);
    
    // close instance of browser
    await browser.close();
}


launchSearch();
