Clicking Through a Dropdown Menu

Hi, I'm new to webscraping and looking for some help.
I'm looking to scrape the information in the table at the URL below, which I can do. However, I want to filter by each sport in the right-hand filter column, and click "Show Results", and scrape each sport individually. Would anyone be able to assist me? I have no idea how to set up the scraper to click through the dropdown as described, and the tutorials don't seem to show that either.
Thanks in Advance!

Url: https://bucscore.bucs.org.uk/BUCSPoints.aspx

This sitemap exports the data I want on the first table, but I don't know how to apply it to each table in the dropdown as described above.
