How can I wait for a JavaScript function to evaluation when scraping a website using Puppeteer/Node.js?

I have a website where I want to manipulate certain user inputs, generate a report by clicking a button, and download the resulting report by clicking on button.

I recorded the user behaviour (manipulation) with Chrome DevTools Recorder, exported the Puppeteer script and adapted it a bit.
Everything works fine, until the report is generated (some JavaScript function is evaluated in the back). Is there any chance to wait for this evaluation to be complete before the script tries to click something which is not yet available?

Here is the code up until I got an error (I redacted the URL for now):

        console.log('Navigating to the target page...');
        await page.goto('https://website.url', { waitUntil: 'networkidle2' });

        console.log('Clicking language selector...');
        await page.waitForSelector('div.active-lang', { visible: true });
        await page.click('div.active-lang');

        console.log('Switching to English...');
        await Promise.all([
            page.waitForNavigation({ waitUntil: 'networkidle2' }),
            page.click('li.en-gb > a')
        ]);

        console.log('Opening report...');
        await Promise.all([
            page.waitForNavigation({ waitUntil: 'networkidle2' }),
            page.click('#treeMenu\:0_4_1_3 a')
        ]);

        console.log('Selecting year...');
        await page.waitForSelector('#input > table:nth-of-type(1) span', { visible: true });
        await page.click('#input > table:nth-of-type(1) span');
        await page.waitForSelector('#yearBeg_0', { visible: true });
        await page.click('#yearBeg_0');

        console.log('Generating report...');
        await page.waitForSelector('td.action_c2 span', { visible: true });
        await page.click('td.action_c2 span', { timeout: 30000, waitUntil: 'networkidle2' });

        console.log('Exporting file...');
        await page.waitForSelector('td.action_c1 span.ui-button-text', { visible: true });
        await page.click('td.action_c1 span.ui-button-text', { timeout: 60000, waitUntil: 'networkidle2' });
        await page.screenshot({ path: 'debug.png_exporting' });

As you can see from the screenshot provided, the evaluation is still not complete:

and this is how it should look like after evaluation:

this is the output from Node after calling the script:

Clicking language selector...
Switching to English...
Opening report...
Selecting year...

I tried with varying timeouts, but this doesn’t seem to change anything.
