Blur Panel not working

[TylerUnity]

I think I'm missing something, but the blur panel isn't working in my project.

Also trying to understand "Blur Material" asset on the "Blur Object". https://github.com/plyoung/UIElements/raw/main/Images/blur3.png

There's a different "Blur Render" material in the other screenshot. Are they different or the same? I didn't see any other reference.

Do you have something in the background to render and create the blurred render texture from? It's been almost a year since I last looked at this so I can not really remember all the small details and guide you.
