Download pdf with python Selenium and Chrome

Question

I have a script that enters a site by Selenium, click on a button that generates the pdf on the site, through the code below I made this pdf be downloaded automatically, but stopped working a few weeks ago, which I need to change so I downloaded the pdf again, I did some tests but nothing worked.

Follow my script:

    **

chrome_options = Options()
        chrome_options.add_argument("--disable-notifications")
        #localização dos donwloads
        download_dir = "C:/downloads"

        chrome_options.add_experimental_option('prefs', {
               "plugins.plugins_list": [{"enabled":False,"name":"Chrome PDF Viewer"}],
               "download": {
               "prompt_for_download": False,
               "default_directory"  : download_dir
               }
        })
