Alert is not being triggered when the learning is assigned by the manager or admin

Summary:

Hi,

Whenever employee is requesting for a learning or withdraws from the learning then the alert is triggered to the line manager and the employee but whenever the line manager or admin assigns the learning to the employee, no alert is triggering to employee or the line manager, the same is happening with the ILT courses that the alert is not being triggered.

Does anyone come across this issue?

Content (required):

I want to trigger the alert whenever the learning has been assigned whether it is ILT or anything else.
