Cannot find element with any selector not even with XPATH (python).

[Mr. GameSucht]

This is the code (python) in which i go to the website "https://aniworld.to/anime/stream/hunter-x-hunter/staffel-2/episode-56" and try to get the fullscreen button in the image below:

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

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument("--start-maximized")
chrome_options.add_extension('D:\Chrome_Bot\extension_5_6_0_0.crx')
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=chrome_options)
driver.get("https://aniworld.to/anime/stream/hunter-x-hunter/staffel-2/episode-56")

input("Press Enter to continue...")

fullscreen_button = driver.find_element(By.XPATH, "/html/body/div[2]/div/div[1]/button[4]")
print(fullscreen_button)

And I get this error message when searching by XPATH:
