customContentStates property
Custom content states that can be used by the user on the content of this call. This can be null if custom content states are disabled in the space of the content. This list can be empty if there are no custom content states defined by the user. This will at most have 3 of the most recently published content states. Only the calling user has access to place these states on content, but all users can see these states once they are placed.
Implementation
final List<ContentState> customContentStates;
