How to Find Blocks

You can use blocks in Gutenberg editor. To find all available Discord blocks open the blocks panel in the builder and scroll to Discord section.

From WordPress 5.8 you can use Gutenberg blocks in sidebar areas. Open widgets panel following Appearance -> Widgets and scroll to Discord section in the widgets list.

Old classic widgets are also available there. Do not mistake them with blocks. They work properly and you can use them, but Gutenberg widgets have more comfortable interface.
