Override or change status of "Not Started" learning assignment to "Completed"

Summary:

Hello,

As per the functionality, when a Learning Admin recommends a course or offering to learners, the initial status of that assignment will be "Not Started." How can the Learning Admin mark this as "Complete"?

There is an action called "Mark Activities Completed." However, after using this action, the assignment status is not updated to "Completed."

Below is the Offerings > Learners page.
