First, there is typo error in doc/source. In doc you use beforeScreenshot, but in code there is beforeScreenShot.
But neither with beforeScreenShot, no log and action happen.

beforeScreenShot: async (page, browser) => {
                console.log('beforeScreenShot');
                await page.click('#myButton');
            },
