title: Change chrome settings (PDF Documents setting) using java selenium
body: <p>I used to be able to click on a button and a PDF file downloaded and then I was able to read it. 
  However, now the PDF opens up in the browser which makes it difficult to read from there because I get a 401. 
  I noticed that I can change the chrome settings to that the PDF document downloads instead of opening in the browser.
  There is a toggle in chrome settings (PDF Documents - "Download PDF Files instead of automatically opening them in Chrome"). This can be found in <code>chrome://settings</code>/.</p>
  
  <p>How can I change it using selenium?
  Can I use <code>ChromeOptions</code>? if yes, how?</p>
  
  <p>Thanks in advance</p>
