Galleries in Lightbox - Linking images

Hey guys, can anybody direct me through the process of creating a gallery using lightbox with the new UI. I am neither able to find the ‘link all lightboxes’ option in the new UI and nor able to find any tutorials with the new UI.

Is it some paid feature that I am missing?

Here is my read-only link - Trishita’s folio
