Atom Feed for assignment deletion

Summary:

Need to detect the deletion of an assignment through atom feeds

Content (please ensure you mask any confidential information):

Hi team,

we can't find the atom feed to detect assignment cancellation.

The atom feed for "Work Relationship Cancellation" exists but the case where only a secondary assignment is cancelled is missing.

Does anyone know which atom feed we could use or any alternative?

Thanks
