Navigating to the Block tab list will display a list of free and pro blocks. Each block item has a title, a description, and a “View Demo” option.
Clicking on “View Demo” will allow you to see the live preview of the corresponding block.
There is also a toggle icon that allows you to either register or deregister a specific block. If you turn on the toggle icon, the corresponding block will be considered a registered block and it will be available in the editor so that you can insert and use.
