Ui-extensions reference within a Ui-extension

When I link up a ui-extension(component) within a ui-extension in the content, the data of the embedded component doesn’t show up. The ‘sys’ property of the data shows up, but the ‘fields’ property doesn’t show which contains the actual component data model. Tried to use the ‘include’ for the deeply nested levels. But it doesn’t work. Stuck in this issue from a long time. Any suggestions would be highly appreciated. Thanks.!

Hey, not sure if you ever resolved this. Any luck? I am wondering how to get a link entry into a contentful extension. Do you have an example of this working?
