How to select subject from an auto complete option?

Website link- https://demoqa.com/automation-practice-form/

I am trying to find xpath for an auto suggested option for Subject field

This is one way of interacting with that dropdown:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys

chrome_options = Options()
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument('disable-notifications')
chrome_options.add_argument("window-size=1280,720")

webdriver_service = Service("chromedriver/chromedriver") ## path to where you saved chromedriver binary
browser = webdriver.Chrome(service=webdriver_service, options=chrome_options)
actions = ActionChains(browser)

url = 'https://demoqa.com/automation-practice-form/'
browser.get(url) 

WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.ID, "subjectsInput"))).send_keys('m')

elusive_el = WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, ".subjects-auto-complete__menu")))
print(elusive_el.get_attribute('outerHTML'))
maths_option = elusive_el.find_element(By.XPATH, "//div[text()='Maths']")
maths_option.click()
print('selected maths')

This should select the Math option, and also print in terminal the html structure of that element, so you can inspect them, and eventually select other child elements as well - you will have to send another string into that input field, wait for the dropdown to initialize, select another option.
