How to add a gallery based carousel?

Hi Team,

We need to showcase 12-15 photos on our homepage from events. We are looking to show them as a carousel so that 3 images show up at once while the images keep changing.

If the user clicks on image, the image gets expanded.

I didn't find any inbuilt block to do this so I used "Carousel" by https://bblockswp.com/docs/carousel-block/

It does the first part but images do not get expanded when clicked by user. Can you suggest something here?
Added the current preview url in private info. Refer bottom most section with image.
