How to implement short codes in to this theme?

I want to implement a before-after plugin (for the image comparison), which works with a shortcode. For example this one, Before After Image Slider Lite – WordPress plugin |

I couldn’t find where and how to insert the short code… I tried directly editing in WordPress and also in additional css. I couldn’t make it work. How can I make the plugin work in such cases?

Thank you,

Hey there,
I hope you’re doing well today

You’ll have to submit a feature request to have this plugin compatible with the theme to our GitHub.

Best Regards,
