By default, the sidekick doesn’t display the newly created components. You need to enable them explicitly in a CQ author instance.

1. Create the component.
2. Using SiteAdmin, open the page that you want to edit in the Author instance.
3. From the sidekick, click the Design tab.
4. In the Design of Paragraph tab that appears, click Edit.

   

5. Find the component based on the ComponentGroup property you defined and enable it.
