In WWDC2020, the video "Synchronizing a local store to the cloud" shows some data fields in the left column of the dashboard, such as CD_post, CD_Tag, where did these come from? need to create it manually on dababoard, or it synchronize from the demo app ?
why do I run this corresponding demo, but there are no data fields in the dashboard of my account
and my dashboard of my account is almost empty?
