get name() {
    return 'flash'
  }
Allow flash on all sites without user interaction.

Note: The flash plugin is not working in headless mode.

Note: When using the default Chromium browser
`pluginPath` and `pluginVersion` must be specified.

Note: Unfortunately this doesn't seem to enable flash on incognito pages,
see [this gist] for a workaround using management policies.

@param {Object} opts - Options
@param {boolean} [opts.allowFlash=true] - Whether to allow flash content or not
@param {boolean} [opts.pluginPath=null] - Flash plugin path
@param {boolean} [opts.pluginVersion=9000] - Flash plugin version (9000 is high enough for Chrome not to complain)

@example
const puppeteer = require('puppeteer-extra')
puppeteer.use(require('puppeteer-extra-plugin-flash')())
;(async () => {
  const browser = await puppeteer.launch({headless: false})
  const page = await browser.newPage()
  await page.goto('http://ultrasounds.com', {waitUntil: 'domcontentloaded'})
})()
