Replace sleep() with WebDriverWait().until() i.e wait for some particular elements to appears

[NavpreetDevpuri]

For example while opening whatsapp sesion, we made it wait until the main windows appear

    try:
        WebDriverWait(browser, 34).until(
            EC.presence_of_element_located((By.CSS_SELECTOR, '[data-testid=menu]'))
        )
    finally:
        return browser
