Workspaces Selector is the building block used to build either Queries or Filters on Workspaces.
Interesting aspect of workspaces are their "Scope": it can be either "ADMIN" (standard workspaces created by admin), "ROOM" (Cells created by users) or "LINK" (public links created by users). Also, please note that the LastUpdated field takes a comparator value (">10d", "<30d" where d is for days").
