In order to export AE animations that can be displayed in the Wallboard application, you will need the Bodymovin extension for After Effects.
You can get Bodymovin extension from the Adobe Store.
You can also review the Adobe installation guide for this extension.
Use the Bodymovin extension to export your animation in Json format.
Upload the exported Json file to the Wallboard system
Select the uploaded Json file for the Adobe widget and it will appear in the content.
You can also download animations from websites which host animations in Json format, such as Lottie Files.
