        </div>

Answer 1

The button is in <a> tag, not <div> tag. You also have only one <div> so div[1] is invalid. You can search by the text

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

button = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, '//a[contains(., "Download bounding boxes")]')))
button.click();

Or by class since you have only one button so class btn should be unique.

driver.find_element_by_class_name('btn').click(); # or 'btn-success' or 'btn-sm'

By the way, click() doesn't return anything, you can't assign it to login_form .

Answer 2

The button is under an <a> tag so we write code for Xpath:

 driver.find_element_by_xpath("//a[. = 'Download bounding boxes']").click()

so it finds the text is "Download bounding boxes" on the website and clicks on it. In the code above // a is written because the button was inside the <a> tag we can write //span , //div as well if the code was under a span or div tag.
