How to add an 'expand section' to Editor X (see example)

Hello,

It would be really cool to have a expand section like this

notice about a third the way down there is the ‘expand light speed story’ button

How to set up a section like this in Editor X please?

Not sure if this can be easily done but likely using Velo (custom code). Have a look here https://www.wix.com/velo/example/hide-%26-show-elements
