Which status must an observation checklist have for its availability to be modified?

For an observation checklist to have its availability modified, it must be in the "Not Started" status. When a checklist is in this state, it indicates that it has not yet been initiated by the user, allowing for changes to be made to its availability, such as adjustments to who can access it or any other modifications related to its setup.

Once an observation checklist is marked as "In Progress," "Completed," or "Queued," it becomes more challenging to modify its availability. In these statuses, the checklist has already been engaged in some capacity or has finished its intended use, leading to restrictions on making further adjustments. Thus, the "Not Started" status is essential for ensuring flexibility in managing the checklist's availability before any actions are taken.
