I think it is great to have a hero block with Carousel or Slider.
It will be suitable for displaying multiple events, promotions, or announcements.
Maybe it will work like this:
Add this Hero slider section
in the hero slider section, we can add or delete slides.
in each slide, we can select a specific post or space
If we add a post, then it brings the cover image or SEO image. Or we can set a new image for the slide.
