Adding captions as an overlay on images and videos using slick and paragraph modules

I’m running Drupal 8.3.2. I created a slideshow using Slick and Paragraphs modules.

Now I want to add captions as an overlay on my image and video slides. I have tried using Slick Media module, but the instructions provided in the project page are not clear.

Can someone guide me on adding slide layouts or captions using Slick Media?
