How to include course or offering flexfield tokens into WLF alert

Summary:

Hello,

We would need to make some update on the alerts delivered by Oracle on OLC module, as the customer would like to include some flexfield they has asked us to include when defining the course or the offering.

Based on Oracle documentation, we see it is supposed to be done. However, we have not been able to include any of them on any notification. We always get a null value. As you see on the image below, it is supposed we could use Offering, Course and Spec flexfields.

Does anyone know how we should refer to them into the template for the notification in order we get the information they have?
