How can I find the element in this page for scraping? - python-3.x

Question

The website is basically a colour swatch as can be seen here:
https://prnt.sc/sux913
Once I get to this page I need to to go through all colours and for the program to provide me with the stock quantity for a size i've specified. (Sometimes somebody wants to know the available quantity in all colours in a large.). At this point i'm pretty lost as i can't find the element i'm meant to be referencing in my code. If the specified size is 'L' , i need to go through each colour and provide the Qty for L. For example, Black L - 9, Navy L - 23, Red L - 334

The last code i tried was as below:
html_content = requests.get(browser.current_url)
print(browser.current_url) # just to check what the URL is
print(html_content.raise_for_status())
soup = bs4.BeautifulSoup(html_content.text, 'html.parser')
ele_color_swatch = soup.select('#prod_color_swatch_area_id')
print(ele_color_swatch)
However, that just gave:
https://www... (some long url)
None
