Announcement bar X button still shows even if isCloseable is set to false.

[GodderE2D]

In my docusaurus.config.js:

announcementBar: {
  id: 'announcementbar',
  content: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Mauris faucibus.',
  backgroundColor: '#25c2a0'.
  textColor: '#2c2f33',
  isCloseable: false,
}

When I visit the site, the announcement bar shows up as expected, however, the X button still appears and when I click it, it disappears, which is not what I want.

Expected

The X button should not be showing and non-functional.

Result

The X button shows, and the announcement bar disappears when clicked.

I am opening a discussion because I have seen other websites with announcement bars that are non-collapsible, but for some reason, this method does not work.
