M365 AuditLogs do not show a CascadeDelete operation

I have a few lists in SPO that are connected (call them Parent, Child1, Child2 for example) via lookup columns. I am trying to implement a delete item action in the parent list that would delete the related items in Child1, Child2 etc., that are pointing to this.

The Cascade Delete operation itself works but when I am reviewing the AuditLogs for the operation, I am only seeing a ListItemViewed operation against the item in the Parent List that I am deleting.

In the browser trace, I can see us making a POST to  /_api/web/lists(@a1)/GetItemById(@a2)/recycle?@a1={LISTID}&@a2={ITEMID} for this action.
