Learning assignment - how to delete an assigment

Summary:

Hi all,

as a learning specialist from My Client Group > Learning > Selecting A course > Learner, I can click change status and withdraw a learner from a course/offering. but I can't set the status to delete.
If I withdraw the assignment the learner will still be able to see the course on the My learning page, is there a possibility that the learner will not see their courses in "withdrawn" status?
Otherwise, is there a possibility of deleting the assignment?

The purpose is not to show the learner courses in which they no longer have an active assignment.

Thank you,
