Hey @travelnitch,
We had to remove the Templates Library in the last version as the templates and the whole thing was pretty outdated. In one of the coming versions, we will re-add new templates as Patterns to allow greater flexibility.
For now, you can find all the templates here in this repository: https://github.com/Codeinwp/gutenberg-templates/tree/master/templates
You can click on each of them to see the screenshot of it. If you like one of them, you can download the .json file and simply drag/drop it to you the editor and the template will be imported.
You can add the “Blocks Export Import” to manually import them.
Let me know if this helps!
