How to find elements that are only available after scrolling using Selenium?

You may create a loop that will scroll to the bottom of the page and search for the element.

The element is being loaded after the scroll, so you need to wait for it. This will make your script slower, but reliable. Create a wait object with a tolerable time delay. As you may need to scroll several times, the time allowed before timeout should be small. I'd suggest you use a wait object created specifically for this purpose, with a 5 or less second timeout.

You also need to set a limit so that it won't be looking forever.

from selenium.common.exceptions import NoSuchElementException, TimeoutException
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

# create a dedicated wait object to wait for a brief period for the elements to be created.
wait = WebDriverWait(driver, 5)
# (...)
# find channel on SCROLLABLE side menu

# limit the number of scrolls
count = 0
while count < 5:
    driver.execute_script("window.scrollTo(0,document.body.scrollHeight);")
    try:
        channel_text = wait.until(
            EC.presence_of_element_located(
             (By.XPATH, f"//*[contains(text(), 'channel-name')]")
            )
        )
        break
    except TimeoutException:
        pass
    count += 1
else:
    # do whatever must be done if the element is never found.
    pass
print(channel_text)

it worked for me, try this

wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("your locator")));
