Carousel elements auto switching not working

I started using webix carousel. One issue which I am currently facing is the carousel content items are not switching automatically unless I click on the nav buttons. I configured scroll speed property as well. Can you please help me on this?

scrollSpeed defines the speed of the animation only. There’s no built-in solution for auto-switch between carousel views, but it’s not a complex task with the existing API:
