By default, the sidekick doesn’t display the newly created components. You need to enable them explicitly in a CQ author instance.
- Create the component.
- Using SiteAdmin, open the page that you want to edit in the Author instance.
- From the sidekick, click the Design tab.
- In the Design of Paragraph tab that appears, click Edit.
- Find the component based on the ComponentGroup property you defined and enable it.
