Can write any other code to move the question in MS-Form using Python selenium, if element class have changed?

Question

I am trying to use Python Selenium to move the question in Microsoft Form by clicking "↓", move-question-down icon (Fig 1).

The HTML structure is in Fig 2 (the code of HTML code in Google Chrome's inspect element is below.)

<div>
    <button aria-disabled="false" aria-label="Move question down" class="css-408">
        <span class="-ge-143">
            <svg viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg" class="-gl-144"><path d="M19.7905 13.26.....20.6862L19.7905 13.2673Z"></path>
            </svg>
        </span>
    </button>
</div>

I have tried to run this code:

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

driver = webdriver.Chrome()
driver.get('https://forms.office.com/Pages/DesignPageV2.....')

driver.find_element_by_xpath('//*[@aria-label="Move question down"]/span[1]/*[name()="svg"][@class="-gl-144"]').click()

It works fine. But I wonder if it can be written more concisely?

And just noticed that the class (class="-gl-144") is not constant. It will change the next day. !!! Why ???

Is there a better way to write?
