Cannot extract/load all hrefs from iframe (inside html page) while parsing Webpage

Question

l am really struggling with this case and have been trying all day. Please l need your help.I am trying to scrape this webpage: https://decisions.scc-csc.ca/scc-csc/en/d/s/index.do?cont=&ref=&d1=2012-01-01&d2=2022-01-31&p=&col=1&su=16&or= l want to get all 137 href-s (137 documents). The code l used:

   def test(self):
        final_url = 'https://decisions.scc-csc.ca/scc-csc/en/d/s/index.do?cont=&ref=&d1=2012-01-01&d2=2022-01-31&p=&col=1&su=16&or='
        self.driver.get(final_url)
        soup = BeautifulSoup(self.driver.page_source, 'html.parser')
        iframes = soup.find('iframe')
        src = iframes['src']
        base = 'https://decisions.scc-csc.ca/'
        main_url = urljoin(base, src)
        self.driver.get((main_url))
        browser = self.driver
        elem = browser.find_element_by_tag_name("body")
        no_of_pagedowns = 20
        while no_of_pagedowns:
            elem.send_keys(Keys.PAGE_DOWN)
            time.sleep(0.2)
            no_of_pagedowns -= 1

The problem is that it loads only 25 first documents (href) and don't know how to do that.
