Extra Content Folder

Hi, I’m looking for the script for the wave effect seen at 1:37 here, but I can’t find the ‘extra content’ folder referred to in the comments. I presume since being added to the Unity Package Manager the included content is different. Is there anywhere else this script can be sourced from?

Cheers!

Thanks @Valjuin , but the script provided in that thread is outdated. I found the folder I was looking for though, as mentioned here: Newb Question: Where are the "TMP Examples & Extras"
