I am new to Beaver Builder and could use some help

I have a series of images that I would like to show as a thumbnail images, and then click on then to make bigger. I found a video that shows me how to do in Beaver Builder, but my menu is different than the video…I can’t find the light box option in my editor…video below…looks simple…but I am at a losshttps://www.youtube.com/watch?v=Ze8YqB4x5nk
