I'm having some difficulty using the AddAttributeAsync() method on the Inspector class. I have tried with different sets of attributes but I can never get the embeddable control to render the fields I have added, it only renders when I have loaded a full layer schema or a mapmember and objectId.
Could anyone provide a sample that shows proper usage of this method? I was presuming it is this call that would provide for displaying a subset of attributes for modification much like the Create Feature experience shows. I didn't see any usage of this method in the community samples projects.
