/*

fazenda.gov.br bypass example with Anti Captcha.

IMPORTANT!
1. Make sure "const userAgent" is same as in your Chromium instance
2. Set your API key ("apiKey")
3. Set correct form password value ("formPassword")
4. The page is using Hcaptcha Enterprise. This is why we do several attempts to bypass the screen (howManyTestsToMake value).
5. If you want to see what's happening, replace "headless: true" with "headless: false".

Install dependencies:

npm install @antiadmin/anticaptchaofficial puppeteer
