Message: no such element: Unable to locate element Selenium Python

I am trying to click on a button but getting this error message: The element I am trying to click does exist on the page but I am not sure why it's saying that the element does not exist:

Message: no such element: Unable to locate element: {"method":"xpath","selector":"//button[@class="vote_button mfp-voteText"]"}

Below is my code:

driver.get('https://trupanion.com/canada/members/contest?pixlee_album_photo_id=427049511')

time.sleep(10)

try:
    vote = driver.find_element_by_xpath('//button[@class="vote_button mfp-voteText"]')
    vote.click()
except Exception as e:
    print(e)

Below is the XPath in chrome dev tool which shows it's correct:

The desired element is within an <iframe> so you have to:

• Induce WebDriverWait for the desired frame to be available and switch to it.

• Induce WebDriverWait for the desired element to be clickable.

• You can use either of the following Locator Strategies:

• Using CSS_SELECTOR:

  driver.get('https://trupanion.com/members/contest?pixlee_album_photo_id=427049511')
  WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe#pixlee_lightbox_iframe")))
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button.vote_button.mfp-voteText"))).send_keys("test")
  

• Using XPATH:

  driver.get("https://trupanion.com/members/contest?pixlee_album_photo_id=427049511")
  WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[@id='pixlee_lightbox_iframe']")))
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[@class='vote_button mfp-voteText']"))).click()
  

• Note : You have to add the following imports :

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
