How to use proxy server while scraping a website using scala scraper?

#1

I'm scraping a website which contains reCAPTCHA and I want to you proxy server while sending scraping request. For this I've used on Free Proxy Server (ZenRows). I'm using JsoupBrowser() and scala (version 2.13.1).

Code:

  val browser = JsoupBrowser()

  val url = "https://abc.com"
  val encodedUrl = Base64.getEncoder.encodeToString(url.getBytes)

  val apiKey = "d4397c47c636b6666627*****"
  val zenrowsUrl = s"https://api.zenrows.com/v1/scrape?key=$apiKey&url=$encodedUrl"

  val doc = browser.get(zenrowsUrl)
  print(doc)

But it is not working. I've seen some other Proxy Servers like Geonode and ProxyEmpire but I've not tested these as they are paid.

Am I doing it in right way or not?
Which server should I use?
