Why is Selenium not finding the button in headless browser mode?

Question

Python

When starting the webdriver in normal mode (the browser window is visible), all buttons are pressed normally, in headless mode it
writes an error:
Message: no such element: Unable to locate element
The code itself:

opts = Options()
opts.add_argument('--headless')
driver = webdriver.Chrome(options = opts)
driver.maximize_window()

The button call itself:

driver.find_element_by_xpath("//*[@id='free_bonus']/div/div[2]/div["+ config["SETTINGS"]["CHOICE_BONUS"] +"]/div[2]/span").click()
