Can I Flag An Item For Follow-Up In A Private Form?

When a Worker is filling out a Private Form, they CAN flag an item for review. Assignees of the flag will be able to access the Follow-up Form and complete it as required.

However, as the original form is Private, the flagged item itself will not be visible to the assignee if they were not the Worker that created the flag in the first place. Instead, they will see a message stating that the flagged item cannot be found, as shown below.
