Templates in Photoshop
Can someone explain how to save templates in Photoshop so they show in the "New Document" dialog like these in the image below?

I don't want any of the ones on Adobe Stock. Not that there is anything wrong with them, they are just not what I need or want. I have created a few .psdt files and dragged them into a library, but that isn't accessible when Photoshop is first opened, you have to open or create a new document first before you can get to the libraries, then you have to navigate to the proper library before you can get to them. I'd like to eliminate all of those steps if possible.
