Webhook for when a Subitem is Restored

I have a database of information that mirrors the information in the subitems of a board. I update the information based on subitem create, update, and delete webhooks. However, in the rare case that a subitem that was deleted is later restored, I want my database to reflect those changes and re-create the subitem there, too.

I can’t seem to see any triggering event for an “undeleted” subitem. Does it exist? Can it exist?

My “create” or “update” triggers are not firing just because an old subitem is restored to the board. And the trigger-when-item-joins-group triggers don’t work because it is a subitem, not an item.

Any help?
