```markdown
I am having issues when adding slides dynamically. I add slides in afterSlide if the user has scrolled to the last slide.
The new slides do get added to the carousel, but sliding/using ref.current.goForward() does not work.
My guess is that it has to do with totalPages not updating and so the carousel thinks there isn't a valid page to go to.

Could you advise if there is any way to make this work?
