Greetings,
I'm using Blender 5.0. All three of the add-ons are not showing when I type them in. Your help is much appreciated.

Hi Torrey ttorreyjproctor ,
It is recommended to use the Blender Version from the Course, especially for beginners like you.
But you can go to your Preferences and if you don't find something in your Addons, above that is the Get Extensions Tab:

I wasn't able to find UVTool Kit. Going to "Get Extensions" worked for the Loop and Bool add-on.
Sometimes, when searching for an add on, it can be easier to search for just part of the name so that if it's in the search under something different than what you thought you can still find it :D
