webscaping

I need someone to build a web-scraping script in Python to extract data from the website https://www.cboe.com/delayed_quotes/meta/quote_table. There are 5 dropdown menus in the middle of the page and the script needs to set all of them as "All". Then click the "View Chain" button. After the page is refreshed properly, click the "Download CSV" button at the button and download a csv file. Thank you!
