Unable to locate element using Selenium and Python

I'm trying to click on an accept cookies button while navigating a webpage using Selenium and Python.

I've used inspect element to find the class name of the button, and then .click() in Python to click on it. It isn't a link, but if it were working the accept cookies pop-up would disappear, and it isn't.

Instead, I'm getting this error:

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"css selector","selector":".SubmitButton CookiePopup-button"}

Here is the code I am running:

cookie_button = driver.find_element("class name", "SubmitButton CookiePopup-button").click()

Thanks for your responses!

You may try this, see if it works

cookie_button = driver.find_element(By.CSS_SELECTOR, "button.SubmitButton.CookiePopup-button").click()
