Can not enter course code into timetable, timetable is returning empty

Question

I am creating a new system for a college timetable, I am looking for free slots in a timetable(where the student has no lectures). I need to enter the course code because at the moment it is opening up a blank timetable, So I need to be able to enter a course code in (e.g CASE2)

Here is my code

from selenium import webdriver 
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager


s = Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=s)
driver.maximize_window() #opens up website, probably not needed. 

driver.implicitly_wait(30)

driver.get('https://opentimetable.dcu.ie/')
df2=pd.read_html(driver.find_element_by_id("week-pdf-content").get_attribute('outerHTML'))[0] 
# currently not searching for anything.

print(df2)
