You pick which ClickUp statuses are visible. The moment a task lands in a status you have chosen to show, such as Client Review, it appears in the portal. As soon as it moves to another status, it disappears. That gives you precise control over what is in front of the client at any time.
On each visible task you also choose what is shown. The description, comments, custom fields, attachments, subtasks, and checklists are all individually toggleable.
