We'll create fresh WordPress site with Carmo Copy to Clipboard installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin will add a new copy to clipboard functionality to Gutenberg Code Block.
It will add a copy button at the top right corner of the block. After clicked, it will select the text, copy to clipboard, and after copy it will deselect the copied text. No markup here.
This plugin makes use of two javascript libraries:
Clipboard.js and Prism.js
