VBCS Find in Files Functionality

Content

Any idea what type of component VBCS is using for Find in Files that overlays the page when you click on it?  It looks like a canvas to me, and I was able to add a canvas to my application using Shay's blog (https://blogs.oracle.com/shay/adding-off-canvas-layout-to-a-visual-builder-application). However, it doesn't do exactly what I want.  I'm trying to mimic the Find in Files functionality such that the box stays visible at the bottom of the page when I move from page to page in my application.  I also want to stay visible if I need to scroll up or down on any page.
